New chiral mono- and bicyclic β-sultams, valuable building blocks for drug synthesis, have been prepared from L-Ala, L-Val, L-Leu, L-Ile, L-Phe, L-Cys, L-Ser, L-Thr, and D-penicillamine by transformation of the COOH group into a methylsulfonyl chloride function, followed by cyclization under basic conditions. Selected properties, derivatives, and reactions of the β-sultams are described.
新的手性单环和双环β -sultams,为药物合成有价值积木,已经从L-丙氨酸,L-缬氨酸,L-亮氨酸,L-异亮氨酸,L-PHE,L-的Cys,L-丝氨酸,L制备-Thr和D-青霉胺,方法是将COOH基团转化为甲磺酰氯官能团,然后在碱性条件下环化。描述了β-合乎目的选择的性质,衍生物和反应。
