SYNTHESIS OF ESTERS OF SUBSTITUTED PHENOLIC ACIDS BY MICROWAVE ASSISTED WITTIG REACTION

摘要

A series of natural and unnatural esters of cinnamic tvcid derivatives were synthesised by the direct Wittig reaction between phenolic aldehydes and (carbalkoxymethyl)-triphenylphosphonium halides in the presence of KHCO_3 or K_2CO_3 using multi-mode domestic oven without isolation of the phosphonium ylides.The compounds were characterised by their UV, NMR and mass spectra.
