Title: The chemistry of thujone : the synthesis of rose oil components and germacrane analogues /

Author: Gunning, Philip James /  Degree: Doctor of Philosophy – PhD /  Program: Chemistry /  Date: 1991

Abstract: This thesis is concerned with the synthesis of natural products from thujone (1), a readily available starting material obtained from Western red cedar. The first part of this study investigates the synthesis of the commercially important fragrances, (β-damascone (8) and β-damascenone (24), which are components of rose oil. Thujone can be efficiently converted to the dimethylated thujone derivative 59 in a two step alkylation process. After the formation of the trimethylsilyl cyanohydrins, 77 and 78, the cyclopropane and isopropyl functionalities were cleaved to give the ketone 103. Further elaboration of 103 gave the key intermediates, 127 and 128. The unsaturated nitriles 128 and 127 can be converted to 8 and 24, respectively, by a reduction to the corresponding aldehydes followed by a Grignard reaction to attach the side-chain and subsequent oxidation. As a model study for the synthesis of 8 and 24 from a cyclohexanone derivative, the nitriles 127 and 128 were efficiently synthesised, in 81% overall yield, from 2,2,6-trimethylcyclohexanone. Formation of the cyanohydrins 149 and 150 was followed by consecutive ‘trans’ and ‘cis’ eliminations to give the nitrile 128. The nitrile 127 was produced from 128 by allylic bromination, followed by hydrolysis and dehydration. A conversion of thujone into the ketone 179, using bromine to effect cyclopropane ring-opening, was also studied. The second part of this study investigates the synthesis of ten-membered rings via a photo-induced oxidative cleavage of the alcohols 245 and 265. Treatment of 245 with lead tetraacetate under ultraviolet irradiation afforded, as the main isolated product, the ten-membered carbocycle 246. Treatment of 265 with iodobenzene diacetate under ultraviolet irradiation afforded, as the main isolated product, the bicyclic alcohol 297.

If you’re looking for US Census data the Oklahoma Dept. of  Libraries  has just updated their site with resources such as “How to use Census data: guides and handouts about data from the U.S. Census Bureau”.

It also includes links to three how-to guides about Census data:  **Choosing Census Data**– How do you choose between Decennial Census data, American Community Survey (ACS) data, and Annual Population Estimates Program (APEP) data? This will help you and your customers make “Best Practices” choices.

**Mixing Census Data Types Together** – Mixing Decennial Census data, ACS data, and APEP data together is a no-no at the Census Bureau. But here at the Oklahoma State Data Center we know that our customers mix different types of Census data together regardless of the statistical inaccuracies of doing so, so we offer this guide to help you work with customers who insist on doing this.

* *Using American Community Survey Data** – How do you work with1-year, 3-year, and 5-year ACS data? This is another “Best Practices” guide. It is essentially the same guide published by ALA/GODORT at http://wikis.ala.org/godort/images/4/42/Beleu-occasionalpaper3.pdf

As part of the UBC Graduate & Undergraduate Student Workshop Series‘ events offered by UBC Library, the next cIRcle workshop is happening today at 3-4:30pm in Scarfe 155 (Neville Scarfe Building).

Would you like to have your academic work searched by Google Scholar or have your work archived in the UBC Library? Then come to this session to find out what cIRcle is, what it contains, how you can contribute and what permissions are required to submit your presentations, articles and reports. This session will be facilitated by Trevor Smith.

The staff of the David Lam Library are moving back to their offices in the new Canaccord Learning Commons on Monday January 31. During the week of January 31, we will be moving in, setting up equipment, and retrieving our book and journal collection from Koerner Library. Staff and student assistants will finalize and train on activities at the new Service Desk, which will be jointly operated with Sauder Learning & Technology Services.

We anticipate that we’ll open the new Canaccord Learning Commons to our users on February 7 or 8. This date depends on some additional sprinkler work which has delayed completion of the space. Soon after our opening, we’ll be inviting students, staff and faculty to attend a small open house in the Learning Commons to celebrate this spectacular and functional new space.

We do have access. Just not as much as advertised.

Unfortunately, many of the coverage dates for CiNii: Open Access Journals in our ejournal A-Z list exaggerate our access. We are working to get these dates corrected. Do continue to let us know when the coverage dates are wrong.

Sorry for any confusion and inconvenience.

Our access to ejournals & ebooks from Emerald has grown.

Along with Emerald Management Plus [ currently offering 225 journals from 24 management disciplines  ] we now have:

  • Emerald Engineering eJournal Collection – includes all 19 journals within Emerald’s engineering, materials science and technology portfolio.
  • Emerald Business, Management and Economics eBook Series Collection – over 550 volumes from more than 70 book series titles. The series features topical, international and authoritative content from many fields including strategy, economics, accounting and finance and human resource management.
  • Emerald Social Sciences eBook Series Collection – includes more than 240 volumes from over 35 book series titles. The collection will be of interest to researchers in the fields of education, environmental management/environment, health care management/healthcare, language and linguistics and sociology and public policy.

All collections can be accessed from our Emerald Resource Page.

This week, we thought that we would post on the Ridington Room, a room in the Barber Centre that is not named after a place in British Columbia.

Rather, the Ridington Room (room 321)  is named after an important person in the history of the University of British Columbia Library: John Ridington.

John Ridington was UBC’s  first University Librarian. A former journalist and teacher, he started work on the library collection in August 1914 when UBC was in its temporary home at West 10th Avenue and Laurel Street (the Fairview Shacks).  By 1916, he had been appointed University Librarian, a position he remained in until his retirement at the age of 72 in April 1940. According to information gathered by the UBC Archives, Ridington was known as a rigid authoritarian and was nicknamed ‘King John’.

In the former Main Library, there was also a room named after Ridington. Photo courtesy of UBC Archives. UBC Archives photo #76.1/22

The University Archives is responsible for collecting material related to the University and, therefore, holds the papers of John Ridington and his family. If you are interested in learning more about the life of UBC’s first University librarian, take a look at the finding aid (“an aid for finding items in an archival collection”) to the collection that is available on the University Archives website.

The Ridington Room is definitely worth a visit if you haven’t already had the oppportunity to see the space. It is often called the “Harry Potter Room” by students, due to the winding staircase and the portrait-covered walls. A portrait of John Ridington, painted in 1912 by his brother-in-law Malcolm Charleston, hangs in the Ridington Room.

There is also a magnificent art installation by Vancouver artist John Nutter, who was commissioned by Jean Barber to to design a 45-panel glass sculpture that is intended to “flow like the Northern Lights,” and features intricate etchings designed around a series of compasses. Nutter felt the Library, like a compass, should be used “as a tool of discovery.”   It is an ideal space for quiet study, but be sure to arrive early because the comfortable chairs fill up quickly!

Chinese Canadian soccer history

A favorite for visitors to the Chung Collection exhibition is the portrait of the 1926 Chinese Canadian soccer team, taken by C.B. Wand. Many are familiar with the history of Chinese Canadian soccer, and those who were not will be now: the 1933 Chinese Students Soccer team has been inducted into the B.C. Sports Hall of Fame.
