中文摘要:
高度,到 chiral N 亚磺酰 imines 的代替的 -diazoacetoacetate 的锂 enolate 的 diastereoselective 增加被开发了。增加产品进一步受到导致相片的 Wolff 重新整理或 Rh (II ) 催化 intramolecular N-H 插入分别地负担得起 chiral 4,5-disubstituted 2-oxo 和 3-oxo pyrrolidines。
英文摘要:
Highly diastereoselective addition of lithium enolate of γ-substituted , & WANG JianBo-diazoacetoacetate to chiral N-sulfinyl imines has been developed. The addition products were further subjected to photo-induced Wolff rearrangement or Rh(II)-catalyzed intramolecu- lar N-H insertion to afford chiral 4,5-disubstituted 2-oxo and 3-oxo pyrrolidines, respectively.
