, p. 8781 - 8788 (2016/10/03)
A rapid construction of quinolone fused heterocycles from single S,N-acetal precursors via double heteroannulation is described. The base, radical and metal-mediated reactions can control the C-N, C-S and C-O bond formations of the S,N-acetal with high chemoselectivity.

Phenylmalonyl heterocyclic compounds such as the quinolones 1a-c or 3, benzoquinolizinones 6a, b and the phenalenones 8a, b can be converted to benzofuranes (2a-c, 7a, b and 9a, b) by cyclodehydrogenation with Pd/C in boiling diphenyl ether. 2-Phenylchinc
