  One-Pot Synthesis of 2-(1,4-Dihydro-2H-3,1-benzothiazin-2-ylidene)propanedioic Acid Derivatives by the Reaction of 2-(1-Bromoalkyl)phenyl Isothiocyanates with Propanedioic Acid Derivatives Using Sodium Hydride

  摘要：

  An efficient one-pot procedure for the preparation of 2-(1,4-dihydro-2H-3,1-benzothiazin-2-ylidene)propanedioic acid derivatives from 2-(1-bromoalkyl)phenyl isothiocyanates with propanedioic (malonic) acid derivatives, such as propanedinitrile, ethyl cyanoacetates, 3-oxo-3-(pyrrolidin-1-yl)propanenitrile and diethyl propanedioate, has been developed. The reactions are carried out in the presence of two equivalents of sodium hydride at -20 degrees C to give the desired products.
