title: Rhodium-catalyzed asymmetric conjugate alkynylation of enones with alkynylsilanols.
abstract: Asymmetric conjugate alkynylation of alpha,beta-unsaturated ketones with (triisopropylsilyl)ethynylsilanols giving beta-alkynylketones took place in high yields with high enantioselectivity in the presence of chiral rhodium catalysts.
