Carbamate derived stable precursors for generating chiral azomethine ylids under mild conditions
摘要:
We describe the evolution of stable azomethine ylid precursors which avoid the need for an aldehyde in the ylid generation step. tert-Butyl carbamate derivative (16) demonstrates comparable efficiency to the standard method of ylid generation and trapping, but permits use of milder conditions.
