An efficient and stereodefined strategy is described for the first asymmetric synthesis of a new type of pyrrolizidine alkaloids, amphorogynine A and its 1-epi-isomer. The key 2,4-disubstituted pyrrolidine ring was constructed by elaboration of the chiral lactam derivative incorporating the d-malic acid-derived skeleton through asymmetric cis-allylation of the functionalized allysilane.
描述了一种有效且立体明确的策略,用于首次不对称合成新型的吡咯嗪核生物碱,两性霉素A及其1-表位异构体。关键的2,4-二取代的吡咯烷环是通过官能化的烯丙基硅烷的不对称顺式-烯丙基化合成掺入了由d-苹果酸衍生的骨架的手性内酰胺衍生物而构建的。
