Reactions of 2-(Diformylmethylidene)-3,3-dimethylindole with hydrazides: synthesis of new pyrazolylindolenine derivatives-the unprecedented one-pot pyrazole-thiadiazole double annulation
A series of new pyrazolylindolenine derivatives has been synthesized through the reaction of 2-(diformylmethylidene)-3,3-dimethylindole (diformyl), prepared by the Vilsmeier reaction, with six different hydrazides. Although the reaction of p-toluenesulfonylhydrazide and S-benzyldithiocarbazide with...
