Samarium Barbier Reactions of α-Iodomethyloxazoles and Thiazoles with Aliphatic Aldehydes
摘要:
The reductive coupling of substituted alpha-iodomethyloxazoles and thiazoles with aliphatic aldehydes under Barbier conditions provides an effective method for the direct incorporation of intact heterocyclic systems.
