Highly substituted polycyclic aromatic and heteroaromatic compounds are produced via a
two-stage tandem benzannulation/cyclization strategy. The initial benzannulation step …

Herein we report an extended study of [4+ 2] benzannulation reactions of 2-(hetero) aryl-
substituted anilines with alkynes by visible light photocatalysis. The method requires the use …

A two-stage “tandem strategy” for the synthesis of indoles with a high level of substitution on
the six-membered ring is described. Benzannulation based on the reaction of …

This article presents a comprehensive review of synthetically useful intramolecular
annulation reactions of nitrene and nitrenoid intermediates leading to heterocyclic …

1236 J. Org. Chem., Vol. 44, No. 8, 1979 Iida, Yuasa, and Kibayashi to a powder. The
mixture was charged to a 100 mL, round-bottom flask equipped with a Dean-Stark trap and …

Polycyclic heterocycles can be formed in good to excellent yields via photochemical
conversion of the corresponding substituted aryl azides under irradiation with purple LEDs …

Bromine induced spiro cyclization of biaryl ynones facilitated the synthesis of spiro [5, 5]
trienones suitable for extended functionality at the C (3′) position. Herein, a step-economic …

A two-stage “tandem strategy” for the regiocontrolled synthesis of very highly substituted
quinolines is described. Benzannulation based on the reaction of cyclobutenones or diazo …

One‐step syntheses of carbocycles substituted with amines from simple starting materials
remain rare. We recently developed an intermolecular [3+ 2] annulation of …
