smoothly, and subsequent base treatment of the Ugi products 10 provided the N-acyloxazolidinones 11 in high yield. The N-acyloxazolidinones derivatives can be reacted with several hetero-nucleophiles, namely, reaction of 11 with thiolates gave thiol ester derivatives 16 efficiently.
Ugi与碳酸酯型异腈9的四组分缩合(4CC)反应顺利进行,随后对Ugi产物10进行碱处理,以高收率提供了N-酰基恶唑烷酮11。N-酰基恶唑烷酮衍生物可以与几种杂亲核试剂反应,即11与硫醇盐反应有效地得到硫羟酸酯衍生物16。
