Inventor: SONG CHOON GEUI
IPC: B01J31/02
Filed: 2016-02-04
Abstract: Disclosed is a production method of an N-protected-beta-amino-dithioester compound. To produce the N-protected--amino-dithioester compound, dithiomalonate may asymmetrically react with N-protected-imine or N-protected-alpha-amidosulfone according to the Mannich reaction in the presence of a chiral catalyst comprising a quaternary amide functional group and a quinuclidine functional group. According to the production method, chiral N-protected-beta-amino-dithioester can be synthesized with high optical selectivity at a high yield using a catalyst which is remarkably inexpensive and safe as compared with conventional metal catalysts.
