- Abstract
The article offers information about synthesis of a new bisspiropyran system derived from benzo(e)pyrrolo(3,2-g)indole. It states that alkylation of hexamethyldihydrobenzo(e)pyrrolo(3,2-g)indole by dibromoethane gives biquaternary salt which was converted by treatment with potassium hydroxide (KOH) into bisanalog of 2-methylene-indoline bases. It also reveals that 2-methyllideneindoline bases are important mediaries in synthesis of various organic compounds.
