摘要

Abstract The chiral biyclic bis-lactams of structures 3 and 4 were synthesized from the key intermediate 2′ b, the N, N′-bis (4-methoxybenzyl) derivative of 2 (X= MeO)(Scheme 6). The synthesis of this intermediate involved two key steps:(1) a double condensation of glyoxylic acid/anisamide (= oxoacetic acid/4-methoxybenzamide) adduct 11c with veratrole (1, 2-dimethoxybenzene; 10) allowed the introduction of two glycine units at the 4, 5- ...
