โœฆ Synopsis

In the presence of base, ethyl 2,2-dihydropoly(per)fluoroalkanoate(2) reacted with Nphenacyl benzimidazole bromide(la-lb),N-acetonyl benzimidazole bromidc(le) and Nethoxycarbonylmethyl benzimidazole bromide(ld) in DMF to give pyrrolo[l,2-a]quinoxaline derivatives(3ae-3dg) respectively.

H and 13C NMR spectra of pyrrolo[l,2-~]quinoxaline and seven of its derivatives have been measured. Assignments of the carbon resonances have been made by correlation of chemical shift and coupling constant data for the pyrroloquinoxalines with those of structurally related pyrrolo[1,2-a]pyrazines a
