Abstract
In this paper, we report the results of heterocyclizations in the pyri do[2,3-b]pyrazine series to give the pyrido[2,3-e] or [3,2-e]pyrrolo[1 ,2-a]pyrazine. The Clauson-Kaas reaction on 2,3-diaminopyridine 2,3 in vestigated; regioselectivity on the 3-amino group is shown by H-1- and C-13-nmr. Synthesis and reactivity of the original pyrazino[2,3-g]ind olizine series is also reported.
