Abstract
Focused on the synthesis of ethyl 2 [3 (1,3 dioxolane 2 yl) 1 hydroxypropylphenyl] 2 methylpropionate. By adding acrolein to the solution of glycol/HBr, 2 (2 bromethyl) 1,3 dioxolane was obtained.The optimum temperature and time of this reaction were found to be 5~10 ℃ and 5~6 h. And Grignard reaction of 2 (2 bromethyl) 1,3 dioxolan with ethyl 2 (4 formyl phenyl) 2 methyl propionate in THF gave ethyl 2 [3 (1,3 dioxolane 2 yl) 1 hydroxypropylphenyl] 2 methylpropionate. The overall yeild was 54 5%.
