Abstract:

A series of t-butylcalix[8]arene 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
