5-(Benzoyloxymethyl)isoxazole-3-carboxylic Acid Ethyl Ester

Molbank
We describe here the palladium hydrogenation of ethyl 5-(benzoyloxymethyl)isoxazole-3-carboxylate. The presence of two reducible sites in the molecule, namely the benzylic-like position and the isoxazole N–O bond, creates a possible competition.

Novel Sulfonium Reagents for the Modular Synthesis of Spiro[2.3]Hexanes and Heteroatom‐Containing Analogues: Synthesis, Application, and Evaluation as Bioisosteres

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Strained spirocyclic spiro[2.3]hexane and its heteroatom‐containing derivatives, including previously underrepresented 5‐oxa‐1‐azaspiro[2.3]hexanes and 1,5‐diazaspiro[2.3]hexanes, were synthesized via a modular approach of insertion of cyclobutane‐, oxetane‐, and azetidine‐containing sulfonium reagents into alkenes, carbonyls and imines.

Side-chain Modifications of Highly Functionalized 3(2H)-Furanones

Molecules, 2012
A series of 3(2H)-furanones, based on side-chain modifications of a parent 3(2H)-furanone, was synthesized in good yield. The parent compound was prepared by hydrogenolysis, and subsequent acid hydrolysis, of isoxazole derivatives.
