the acylation reaction of the aza-allyl anions derived from 1 and 2 have been studied. Under suitable reaction conditions, oxazoles 5, α,α-disubstituted α-acyl-α-amino acid derivatives 3, and α,β-didehydroamino acid derivatives 7 can be prepared. A new 1,3-diamino-2-propanol derivative 8 was isolated by reaction of the C-acyl intermediate derived from N-[bis(methylthio)methylene]- benzylamine 2 and
已经研究了衍生自1和2的氮杂烯丙基阴离子的酰化反应的新方面。在合适的反应条件下,可以制备恶唑5,α,α-二取代的α-酰基-α-氨基酸衍生物3和α,β-二氢化氢氨基酸衍生物7。通过原位加成-环缩合串联反应,衍生自N- [双(甲硫基亚甲基)亚甲基苄胺2的C-酰基中间体与阴离子2反应,分离出新的1,3-二氨基-2-丙醇衍生物8。
