✦ Synopsis

Abstract

Key steps of the synthesis are the regioselective hydrolysis of biscarboxylate (III), the monoacyl azide formation and subsequent Curtius rearrangement to give isocyanate (VI), and the sequential ring closure to give carbonylbis(dihydrothienopyrrole) (X) (and the carbonylbis(dihydrofuropyrrole) analogously).
