A catalytic, aerobic oxidative dearomatization protocol has been developed for the preparation of spiroisoxazline scaffolds from oximes using TEMPO and NaNO2 as the catalyst and O2 as the sole oxidant. This dearomatization methodology features its mild reaction conditions, good functional group tolerance, and an unprecedented broad substrate scope, encompassing phenols, aryl ethers, thiophenols, aryl
已经开发了一种催化的好氧氧化脱芳香化方案,用于使用TEMPO和NaNO 2作为催化剂,O 2作为唯一的氧化剂,从肟中制备螺异异唑啉支架。该脱芳香化方法的特点是反应条件温和,官能团耐受性好,底物范围空前,涵盖酚,芳基醚,硫酚,芳基硫化物等。
