A Short Synthesis of (±)-Matrine

Angew Chem Int Ed Engl. 1998 May 4;37(8):1128-1131. doi: 10.1002/(SICI)1521-3773(19980504)37:8<1128::AID-ANIE1128>3.0.CO;2-P.

Abstract

Three different radical reactions were used in a short total synthesis of (±)-matrine (1). Two of the four six-membered rings and four new bonds were created in one radical cascade involving intermolecular addition followed by two successive cyclizations and transfer of a xanthate group.
