Abstract

First asymmetric synthesis of (−)-chicanine has been accomplished in 14 steps by employing the Evans asymmetric syn-selective aldol reaction, diastereoselective hydroboration and an regioselective, intramolecular Mitsunobu etherification. The absolute configuration of (+)- and (−)-chicanine has been revised to 2R,3S,4R,5R and 2S,3R,4S,5S, respectively, through CD analysis.
