摘要：

Diazo-transfer reaction of tosyl azide and alkyl 2-cyanoacetates in the presence of pyridine at 0 degrees C gives the corresponding alkyl 2-cyano-2-diazoacetates. This material readily undergoes nucleophilic attack by pyridinium 1-cyano-2-alkoxy-2-oxoethan-1-ide to form dialkyl (Z)-3-amino-2-cyano-4-diazopent-2-enedioates. The X-ray structure of a typical product is reported, as well as DFT computational studies that illuminate the structural features of these stable diazo compounds.
