The "pull-push" effect of the Bpin moiety in ArE-Bpin reagents (E=Se, S) is demonstrated by the Lewis acid interaction with the carbonyl group of ynones and the concomitant delivery of ArSe or ArS to the electron-deficient alkyne with impressive stereosel
Facial selectivity and stereospecificity in the (4 + 3) cycloaddition of epoxy enol silanes

The scope of the (4 + 3) cycloaddition using epoxy enol silanes has been examined. Unhindered and nucleophilic dienes react to give the highest yields, but hindered dienes give rise to higher diastereoselectivities. Notably, the cycloaddition shows facial
