چکیده
Asymmetric Michael reactions of thiols with enones were catalyzed by a Sc(OTf)(3)-chiral bipyridine complex at room temperature in water without using any organic solvents, to afford the desired sulfides in high yields with high enantioselectivities.

Chiral-Sc catalyzed asymmetric Michael addition/protonation of thiols with enones in water.
Asymmetric Michael reactions and enantioselective protonations between enones and thiols were catalyzed by a Sc(OTf)(3)-chiral 2,2'-bipyridine complex in water. The remarkable governing of the enantioselectivity for simple introduction of protons despite their abnormally high mobility in water may provide us with new synthetic opportunities as well as significant chemical advances.
