6-carbethoxy-5-(3'-bromophenyl)-3-aryl-2-cyclohexenones 2a-j were obtained from the1-aryl-3-(3'-bromophenyl)-2-propene-1-ones 1a-j by micheal addition of ethyl acetoacetate, followed by internal claisen condensation. reaction of 2a-j with hydrazine hydrate afforded the corresponding 6-aryl-4-(3'-bromophenyl)-3-oxo-2,3a,4,5-tetrahydro-2h-indazoles 3a-j. the structures of newly syn...
