“…of chiral allylic alcohols and amines is performed in the presence of Ti(OPr-i) 4 , in situ epoxidation occurs, affording highly threo (ca 95%) diastereoselective ene reactions with respect to the OH or NHR functionality, by generating two new stereogenic centres with high stereoselectivity 4 . Similarly, regiospecific reactions with vinylic silanes 195 , stannanes 196 and sulphoxides 197 afford allylic alcohols, epoxy alcohols or trimethylsilyl enones 198 , with high stereospecificity, which are very useful building blocks in organic synthesis. Regiospecific reactions of vinylsilanes with 1 O 2 have been used 199,200 by Paquette and coworkers for the regiospecific production of trimethylsilyl allylic alcohols whose subsequent desilylation resulted in a novel methodology for carbonyl transposition.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.
