Diacetone-D-glucose-mediated Asymmetric Syntheses of N-Carboxyalkylated and O-Carboxyalkylated Flavones

摘要

A number of Oalkylated and N-alkylated flavones have recently been prepared to improve the biochemical and pharmacological properties of naturally occurring flavones.In particular O-carboxyalkylated flavones have attracted high interest not only for their interesting bioactivities,but also as valuable intermediates for further synthetic elaboration of flavone derivatives.
