route for the modular synthesis of (R)-3-hydroxyalkanoic acids, constituents of the naturally biodegradable poly(3-hydroxyalkanoate) polymers, and its application to the synthesis of (R)-3-hydroxydecanoic acid is described. Key steps include a microwave-assisted catalytic transfer hydrogenation and a facile microwave-assisted hydrolysis of an N-methoxy-N-methyl (Weinreb) amide, which enhances the practicality
描述了模块化合成(R)-3-羟基链烷酸,天然可生物降解的聚(3-羟基链烷酸酯)聚合物组成的通用途径及其在合成(R)-3-羟基癸酸中的应用。关键步骤包括N-甲氧基-N-甲基(Weinreb)酰胺的微波辅助催化转移氢化和微波辅助水解,这增强了该保护基团对羧酸的实用性。
