Rh(III)‐Catalyzed [4 + 3] Annulation for Construction of Heterocycle‐Fused Azepines

Advanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.
Rhodium(III)‐catalyzed [4 + 3] annulation of 2‐arylquinazolinones with allyl ethers enables the facile synthesis of heterocycle‐fused azepines. This step‐economical protocol proceeds via CH and NH functionalization, accommodating diverse heteroatom‐ and polyaromatic‐substituted substrates to deliver structurally varied fused azepines efficiently and ...

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

Chirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Strategies Toward Accessing Enantioenriched (Hetero)Benzo‐Fused 5‐ and 6‐ Membered Rings via Intermolecular Carbometalation

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
The use of transition‐metal catalysts and design of chiral ligands have allowed chemists to access highly functionalized benzofused 5‐ and 6‐ membered rings in high yield and enantioselectivity. A common strategy used relies on an intermolecular carbometalation across alkynes and olefins, usually followed by a subsequent intramolecular carbometalation.

Crystal structure of 2-(5-methoxy-1-benzofuran-3-yl)acetic acid

Acta Crystallographica Section E: Crystallographic Communications, 2015
The benzofuran residue in the title compound, C11H10O4, is essentially planar (the r.m.s. deviation for the nine non-H atoms = 0.011 Å). While the methoxy group is coplanar with the fused ring system [C—C—O—C torsion angle = 3.1 (3)°], the acetic acid ...
