Abstract An improved synthesis of the 7,6‐fused bicyclic lactam is presented starting from readily available chiral starting materials. (S)‐allylglycine is protected as the phthalimide derivative and coupled with (S)‐2‐amino‐6‐hydroxyhexanoic acid methyl ester. Oxidation of the hydroxyl group to the aldehyde followed by enamide synthesis and acyl iminium ion cyclization provide the bicyclic system
摘要 7,6-稠合双环内酰胺的合成方法以现成的手性原料为起始原料。(S)-烯丙基甘氨酸被保护为邻苯二甲酰亚胺衍生物并与 (S)-2-氨基-6-羟基己酸甲酯偶联。将羟基氧化成醛,然后进行烯酰胺合成和酰基亚胺离子环化,以良好的总产率提供双环体系作为单一非对映异构体。
