Über die Umsetzung des Nα-Tosylglycinäthylester-isonicotinoylhydrazons mit Hydrazin und Hydrazinabkömmlingen

摘要

Nα-Tosylglycine ethyl ester isonicotinoylhydrazone (1) undergoes hydrazinolysis both of the C,N double bond and of the ester bond to yield as major product the unstable hydrazidine2, which reacts in a known manner to yield4and5
