Synthesis of the novel benzothiazole compounds from 7-benzylidenebicyclo [3.2.0] hept-2-en-6-ones and 2-aminobenzenethiol
Synthesis of the 2-(2-styrylcyclopent-3-enyl)benzo-[d]thiazoles (6a-i) is reported for the first tone. Reaction of 7-benzylidenebicyclo [3.2.0] hept-2-en-6-ones (3a-i) and 2-aminobenzenethiol (4) in the presence of p-TsOH as a. catalyst, in ethanol under reflux, resulted in the formation of novel 2-(2-styrylcyclopent-3-enyl)benzo[d]thiazoles in high yields.
