The hydroxyl and aldehyde groups of 2-hydroxybenzaldehydes were protected by the reaction with Fischer's base and deprotected by the ozonolysis in methanol at −78°C to give the corresponding 2-hydroxybenzaldehydes in good to high yields.
2-羟基苯甲醛的羟基和醛基可通过与Fischer碱的反应进行保护,并通过在-78°C的甲醇中进行臭氧分解来脱保护,从而以高至高收率得到相应的2-羟基苯甲醛。
