[reaction: see text] An efficient total synthesis of (2S,2'S,3aR,3'aR,8aR,8'aR)-6,6'-dichloro-3a,3'a-dihydroxy-1,1',2,2',3,3a,3',3'a,8 ,8a,8',8'a-dodecahydro-5,5'-bipyrrolo[2,3-b]indole-2,2'-dicarboxylic acid, the central amino acid component of chloptosin (1), is described. Starting from m-chloronitrobenzene, this C(2)-symmetrical amino acid was synthesized by using a 14-step route, in which a Zinin
