E. Desarbre et Jy. Merour, PALLADIUM HETEROANNULATION PROCESS FOR SYNTHESIS OF SUBSTITUTED PYRROLO [2,3-B]PYRIDIN-3-ONES, Tetrahedron letters, 37(1), 1996, pp. 43-46
Substituted-3H-pyrrolo[2,3-b]pyridin-3-ones 7b-d were prepared from 2-
amino-3-iodopyridine derivatives 3b-d by palladium carboannulation pro
cess with allenic compounds and then oxidative cleavage of the exocycl
ic carbon-carbon double bond.
