Modular syntheses of isoxazoloazepinones and pyrazoloazepinones
摘要:
Herein we described an optimised synthesis of isoxazoloazepi none and novel heterocycle pyrazoloazepinone. These syntheses are modular in nature and fast to execute. The title compounds were obtained pure without the intervention of chromatography. (c) 2007 Elsevier Ltd. All rights reserved.
A method allowing the selective oxygen labelling of aliphatic polyacids, for example, succinic and glutaric acids, is reported. This process is based on the hydrolysis of a 3-alkyl-4-nitroisoxazol-5-yl group by Na18OH and affords the products in high yields. The same procedure was applied for the preparation of labelled aliphatic carboxylic acids.
