Process Improvement on the Synthesis of t-Butylcalix arene Ester Derivatives and Their Extraction Performance for Ester Catechins
Chinese Journal of Synthetic Chemistry, pp. 68-70+74, 2009.
A series of t-butylcalixarene ester derivatives(2a~2e) were synthesized using acyl chlorides as acetylating reagents,using triethylamine as a catalyst and an acid binding agent. The structures were characterized by 1H NMR,IR and elemental analysis. Distribution behaviors of ester catechins monomers were investigated using 2 as an extra...More
