trans-4-hydroxylpyrrolidine lactams 1 starting from amino acid is described. The utility of this method has been demonstrated in the synthesis of antipsychotic nemonapride 3 and antiangiogenic streptopyrrolidine 4. Compared four synthetic stereoisomers of natural streptopyrrolidine 4 in term of spectroscopic and physical data, the absolute structure of the natural product was proposed as (4S,5S)-configuration
描述了一种从氨基酸开始反式-4-羟基吡咯烷内酰胺1的有效方法。该方法的效用已被证明在抗精神病药物的齐拉西合成3和抗血管生成streptopyrrolidine 4。从光谱和物理数据方面比较了天然链霉菌吡咯烷4的四种合成立体异构体,提出了天然产物的绝对结构为(4 S,5 S)-构型。
