Directed Functionalization of Cyano-Substituted Furans and Thiophenes with TMPMgCl·LiCl
摘要:
A number of novel difunctionalized furans and thiophenes has been prepared by the reaction of the cyano-substituted substrates with TMPMgClLiCl followed by the reaction with electrophiles. The crucial metalation step takes place under mild conditions allowing the isolation of desired derivatives in reasonable to good yields.
