An improved method for direct conversion of heteroaryl-aldehydes to heteroaryl-acetonitriles
摘要:
Treatment of heteroaryl-aldehydes with diethyl cyanophosphonate in the presence of a catalytic amount of LiCN affords phosphorylated cyanohydrins which are reduced in situ with SmI2 to give heteroaryl-acetonitriles in generally good overall yields (50-100%). The generality of the process is demonstrated. (C) 2003 Published by Elsevier Science Ltd.
