The totalsynthesis of (+)-yohimbine was achieved in 11 steps and 14% overall yield. The absoluteconfiguration was established through a highly enantioselective thiourea-catalyzed acyl-Pictet-Spengler reaction, and the remaining 4 stereocenters were set simultaneously in a substrate-controlled intramolecular Diels-Alder reaction.
