Application:	3-Butyn-2-one was used in the synthesis of clerodane diterpenoid (+/-)-sacacarin. It was used as substrate in stereoselective, conjugate arylation mediated by gallium(III) chloride leading to (E)-α,β-unsaturated ketones.
General description:	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.
Packaging:	2.5, 10 mL in glass bottle
