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.

BC Nursing Leadership Institute: program evaluation report in cIRcle!

Background:

The first BC NLI pilot was conducted in March 2005 with 25 first-line nurse leaders. Successful evaluation outcomes resulted in 13 additional sessions between March 2006 and March 2010: three sessions annually with an average of 35-40 first-line nurse leaders in attendance.

Based upon the four major components of the BC NLI: a) a 4-day residential workshop, b) mentoring supports at practice sites, c) year-long leadership projects at practice sites, and d) an online knowledge network with a discussion forum, resources, and a facilitator or knowledge broker (KB).

What you’ll discover in this report:

• Executive Summary

• Key Outcomes

• Notable Findings and Implication

• Key Recommendations

UBC Dentistry Research Day 2011 is on Tuesday, January 25th!

This day highlight[s] the research being done by several members of UBC’s ELDERS (Elders Link with Dental Education, Research and Service) Group, a multidisciplinary team which draws on expertise from many faculties.

The Faculty of Dentistry is honoured to include presentations on this pressing concern from a diverse and complementary group of full-time faculty, along with Dr. Lynn Beattie and Hamber Visiting Professor Dr. Asuman Kiyak. Beattie is professor emeritus, UBC Department of Medicine, Division of Geriatric Medicine, and Kiyak is professor and director of the Institute on Aging at the University of Washington, Seattle.
