A One-Pot Umpolung Method for Preparation of α-Aryl Nitriles from α-Chloro Aldoximes via Organocuprate Additions to Transient Nitrosoalkenes
摘要:
Conjugate addition of a variety of aryl lithiocyanocuprates to nitrosoalkenes generated from alpha-chloro aldoximes, followed by in situ dehydration of the crude alpha-aryl aldoxime product with N,N'-dicyclohexylcarbodiimide, affords alpha-aryl nitriles in good overall yields via a one-pot protocol.
