Emergency medicine training in Canada: a survey of medical students' knowledge, attitudes, and preferences.

Objectives: The objective of this study was to assess medical students' knowledge of and attitudes toward the two Canadian emergency medicine (EM) residency programs (Fellow of the Royal College of Physicians of Canada [FRCPC] and Certificant of the College of Family Physicians-Emergency Medicine [CCFP-EM]). Additionally, medical students interested in EM were asked to select factors affecting their preferred choice of residency training program and their intended future practice.

Methods: Medical students enrolled at The University of Western Ontario for the 2008-2009 academic year were invited to complete an online 47-item questionnaire pertaining to their knowledge, opinions, and attitudes toward EM residency training.

Diene-transmissive cycloadditions: control of monocycloaddition by self-assembly on a Lewis acid template.

The sequential control of diene-transmissive Diels-Alder reactions to expand their versatility for natural product synthesis and the preparation of diversity oriented libraries is described. Self-assembly of the components (trienol 5 and methyl acrylate) via a Lewis acid template proceeds with regio-, diastereo-, and enantioselective [(S)-BINOL added] control to the monoadduct. In contrast, no cycloaddition reaction occurred at 22 degrees C in the absence of catalyst.
