The totalsynthesis of iheyamine A from readily available ethyl 2-aminocinnamate and 5-methoxyindole-2-carboxaldehyde is described. The cyanide-catalyzed imino-Stetter reaction of an aldimine derived from ethyl 2-aminocinnamate and 5-methoxyindole-2-carboxaldehyde provided the desired unsymmetrical 2,2′-bisindole-3-acetic acid derivative. The subsequent introduction of an amino group at the C-3′ position

high-yielding total asymmetric synthesis of (−)-martinellic acid is reported. The conjugate addition of lithium (R)-N-allyl-N-(α-methyl-4-methoxybenzyl)amide to tert-butyl (E)-3-[2′-(N,N-diallylamino)-5′-bromophenyl]propenoate and alkylation of the resultant β-amino ester have been used as the key steps to install the C(9b) and C(3a) stereogenic centers, respectively, and a highly diastereoselective
