Regioslective Hydride Reduction of 2-(N-cyanoimino)thiazolidine Derivatives
摘要:
Treatment of 3-alkyl-2-(N-cyanoimino)thiazolidines with lithium aluminum hydride caused reductive cleavage of the imino double bond to afford 3-alkylthiazolidines, while diisobutylaluminum hydride reduction of 3-alkyl- and 3-sulfonyl derivatives resulted in the nitrile reduction or imino-nitrile bond cleavage to give 2-formyliminothiazolidines and/or 2-iminothiazolidines.
