Abstract:

Intramolecular cyclization of 1-amino-3-phenacyl-4-carbohydrazido-1,2,3-triazolium-5-olates has been shown to take place via selective interaction of the carbonyl group with the terminal amino function of the hydrazido group to form a 1,2,5-triazepine ring. Minor products, resulting from the interaction of the a-nitrogen atom of the hydrazido group with the carbonyl function, having a N-aminopyridazine structure were also detected and isolated. A general method for the synthesis of novel mesoionic 2-amino-7-aryl-4-oxo-2,4,5,8-tetrahydro{[}1,2,3]triazolo{[}5,1-d]{[}1,2, 5]triazepin-9-ium-3-olates was developed. (C) 2004 Elsevier Ltd.
