Synthesis of the antifungal 1-benzoxepin pterulone

Tetrahedron, 2001
Abstract The chlorinated 1-benzoxepin derivative pterulone ( 1a ), a potent antifungal metabolite isolated from a Pterula species, was synthesised from 4,5-dihydro-2 H -benzoxepin-3-one 6 by the oxidation of 6 to 3(2 H )-oxepinone 7 , a Wittig reaction that transformed the keto functionality of 7 to a chlorovinyl group, and a Friedel Craft's

An Efficient Approach for the Construction of Benzazepine and Benzoxepine Derivatives

Chemistry – An Asian Journal, 2012
AbstractA novel and facile synthetic protocol for the construction of benzazepine and benzoxepine derivatives through a copper(I)‐catalyzed reaction of 2‐(2‐ethynylphenyl)‐1‐tosylaziridine or 2‐(2‐ethynylphenyl)oxirane with sulfonyl azides is disclosed. A ketenimine is the key intermediate during the reaction process.

Theoretical study of rhodium(III)-catalyzed synthesis of benzoxepine and coumarin

Journal of Molecular Modeling, 2020
The mechanisms of the rhodium-catalyzed cycloaddition of 2-vinylphenol with diphenylacetylene and carbon monoxide have been studied using density functional theory calculations at the B3LYP/6-31G (d, p) (Lanl2dz for Rh) level of theory. The SMD solvation model was used in MeCN solvents at M06-2X/6-311 ++ G (d, p) (Lanl2dz (f) for Rh) levels using a ...
