Beschreibung

Allgemeine Beschreibung

3-Butyn-2-one undergoes asymmetric double-Michael reaction with ortho-tosylamidophenyl malonate catalyzed by chiral aminophosphines to yield indolines. It undergoes double Michael reaction with nitrogen-containing tethered diacid to give pipecolic acid derivatives.

Anwendung

Substrate in a stereoselective, conjugate arylation mediated by gallium(III) chloride leading to (E)-α,β-unsaturated ketones.
