The Baylis-Hillman Bromides as Versatile Synthons: A Facile One-Pot Synthesis of Indolizine and Benzofused Indolizine Frameworks

A facile one-pot synthesis of indolizine, benzofused indolizines {pyrrolo[1,2-a]quinoline and pyrrolo[1,2-a]isoquinoline} derivatives from the Baylis-Hillman (B-H) bromides, via an interesting strategy involving 1,5-cyclization of nitrogen ylides has been described.
