title: The effect of alkynyl groups on torquoselectivity. Highly stereoselective olefination of alkynyl ketones with ynolates.
abstract: We have shown the first experimental evidence of the alkynyl substituent effect on torquoselectivity and succeeded in effecting the highly torquoselective olefination of alkynyl ketones to provide functionalized tetrasubstituted olefins.
