Reaktionen von 5‐diazourazilen mit primären aminen zu 1,2,3‐triazolcarbonsäurederivaten

Abstract

Abstract The reaction of 5‐diazouracils with saturated primary amines affords [(1‐alkyl‐1,2,3‐triazol‐4‐yl) carbonyl]ureas. The primary formation of a non‐isolable 6‐amine‐adduct 2 is followed by 1,6‐ring opening of the pyrimidone and ring closure to the triazole derivative.
