	1	Quinoxaline-specific enantioselective sulfa-michael reaction catalyzed by chiral phosphoric acid显示文摘Highly enantioselective sulfa-Michael additions(SMA)between 2-alkenyl quinoxalines and aromatic thiols are accomplished using a low loading of chiral phosphoric acid catalyst(1 mol%).It was confirmed by an investigation of a lot of azaarenes that the two C-N units of quinoxalines are indispensable for controlling the reaction enantioselectivities.A series of non-terminal 2-alkenes substituted with aryls or alkyls,even other electro-withdrawing groups such as ketones,esters,or amides,selectively reacted and afforded the desired SMA products(48 examples)in good regioselectivities with high yields(up to 99%)and good ee values(up to 97%).
