Study on the synthesis of esculetin under microwave irradiation

YANG Xiao-jun,GAO Huan-huan(School of Chemistry and Chemical Engineering,Yan'an University,Yan'an 716000,China)  
Esculetin was obtained by the cyclization of 1,2,4-benzenetriol and ethyl propionate using ZnCl2 as catalyst under microwave irradiation.The optimum reaction conditions were as follows:n(1,2,4-benzenetriol) ∶n(ethyl propionate)=1.0∶1.0,3.5 g ZnCl2,10 min,105 ℃ and microwave power 400 W.The yield reached 87.4 %.
