We present a convenient synthesis of novel pyrrole- and indole-fused 1-oxo-1,2,3,4-tetrahydropyrazine heterocyclic structures using a novel modification of four-component Ugi condensation. We demonstrate the usefulness and versatility of the developed approach for the synthesis of variously substituted compounds, and discuss the scope and limitations of the chemistry involved.

Accomplished herein is a rearrangement strategy for the highly efficient assembly of synthetically cumbersome while medicinally significant 2-amino-3-formyl chromones via palladium-catalyzed ring-opening, rearrangement, and cyclization process. Such a sequence enables the formation of one C(sp2)–O bond and one C(sp2)–C(sp2) bond, and reconstruction of the benzo-γ-pyrone moiety in a single operation
