Palladium-Catalyzed Sequential Alkylation−Alkenylation Reactions. Application to the Synthesis of 2-Substituted-4-Benzoxepines and 2,5-Disubstituted-4-Benzoxepines

The Journal of Organic Chemistry, 2002
The synthesis of 2-substituted-4-benzoxepines and 2,5-disubstituted-4-benzoxepines from aryl iodides and bromoenoates is described. This methodology is based on a palladium-catalyzed aromatic substitution followed by an intramolecular Heck sequence. Under the reaction conditions (Pd(OAc)(2) (10 mol %), tri-2-furylphosphine (20 mol %), norbornene (2 ...

Synthesis of Benzoxepine Derivatives via Two‐Fold Tandem Metathesis

ChemistrySelect, 2023
Abstract Herein, we report the synthesis of the benzoxepine derivatives via a two‐fold ring rearrangement metathesis (RRM). Using the ring strain as deriving force, we provide a useful approach to assemble the seven‐membered benzo‐oxepine derivatives that are otherwise difficult to realize due to unfavorable entropic reasons.

Benzoxepin-Derived Estrogen Receptor Modulators:  A Novel Molecular Scaffold for the Estrogen Receptor

Journal of Medicinal Chemistry, 2004
We present and examine the efficacy of a novel benzoxepin-based scaffold for modulation of the human estrogen receptor. Receptor tolerance of this new molecular scaffold is examined through presentation of experimentally determined antiproliferative effects on human MCF-7 breast tumor cells and measured binding affinities.

Synthesis and Antifungal Activity of Chromones and Benzoxepines from the Leaves of Ptaeroxylon obliquum

Journal of Natural Products, 2020
This study reports the first total synthesis of the bioactive oxepinochromones 12-O-acetyleranthin (8) (angular isomer) and 12-O-acetylptaeroxylinol (9) (linear isomer). The antifungal activity of these compounds and their derivatives was determined against Candida albicans and Cryptococcus neoformans.
