original stereocontrolled transannular rearrangement starting from activated 2,5-diketopiperazines has been developed, an opportunity for the medicinal chemistry field, which requests access to novel biological scaffolds. This powerful ring contraction, which can be related to a stereoselective aza-version of the Chan rearrangement, allows for example the one-step synthesis of various tetramic acids, access
从活化的2,5-二酮哌嗪开始的有效且原始的立体控制的跨环重排已被开发,这对于药物化学领域来说是一个机会,该领域要求获得新型的生物支架。这种强力的环收缩可能与Chan重排的立体选择性氮杂相关,例如可以一步合成各种四酸,获得2-二取代他汀类药物,或合成相关的内酰胺约束的二肽模拟物。使用TRAL-RCM序列。
