Reduction of Δ2-Isoxazolines to β-Hydroxy Ketones with Iron and Ammonium Chloride as Reducing Agent
摘要:
A detailed study of a procedure for the selective reduction of Delta(2)-isoxazolines to the corresponding beta-hydroxy ketones is reported. The use of iron and ammonium chloride as the reducing agent in the presence of water results in a facile and chemoselective protocol for the preparation of beta-hydroxy ketones, including the conjugated beta-hydroxy ketones.
