clear yellow to orange-brown liquid | [Uses]
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. | [Definition]
ChEBI: Butyn-2-one is a methyl ketone and a terminal acetylenic compound. It is functionally related to a butan-2-one. | [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. |
