Abstract

The reaction of 1-benzyl-2,3-dioxopyrrolidine with aromatic dimnines as a means of preparing polycyclic molecules containing the pyrrolo[2,3-b]pyrazine moiety has been studied as a model route to molecules isomeric with the biologically active pyrrolo[2,3-d]pyrimidines. The spiro derivatives 17-19, however, have been the realized products rather than the desired linear systems (e.g., 9).
