A reinvestigation of the preparation and reaction of ethyl 2-substituted styrl-4-ozoquinazoline-3-(4-benzoates) with hydrazine hydrate. The preparation and reactions of 2-arylsulfonylvinamidinium salt
Abstract
The first part of this report discusses the preparation and reaction of various ethyl 2-substituted styryl-4-oxoquinazoline-3- ( 4-benzoates) with hydrazine hydrate to yield the novel tricyclic compound 2,3-dihydro-2-substituted phenyl-9H-pyrazolo [3,2-b] quinazoline-9-one and not the 2-substituted styryl-3-(4- benzhydrazide)-4-quinazoline as reported earlier. Complete spectral data for these compounds and probable mechanism of formation of these compounds are also included. The second part of this report describes the preparation of 2- pheny ls ulf ony l vinamidini um salt and its reaction with various Grignard reagents to give a convenient one pot synthesis of 1- dimethylamino-2-phenylsulfonyl-4-alkyl substituted-1,3- butadienes in high yield. It also describes the reaction of sodium borohydride with 2-phenylsulfonylvinamidinium salt to give 1, 3- dimethylamino-2-phenylsulfonyl- l-propene and its further reaction with various sulfur nucleophiles. Complete spectral data and the probable mechanism of formation of these compounds are also included.
