Two tricyclic adducts from consecutive additions of dimethyl acetylene-dicarboxylate to 2,4-di-t-butyl-3a,5a-dihydro-3H-cyclobuta[b]pyrrole: A novel formation of cyclobuta[1',2'-f]pyrrolo-[1,2-b]oxazine derivative

Abstract

The tricyclic heterocycles (2) and (3) were newly synthesized by the addition reaction between 2,4-di-t-butyl-3a,5a-dihydro-3H-cyclobuta[b]pyrrole (1) and dimethyl acetylenedicarboxylate (DMAD). The structures were confirmed by the X-Ray structural analyses, and the pathway affording them was also proposed.
