The reaction of cyclic ketene acetals with methanol gave the corresponding cyclic orthoacetates in fairly good yield. The linear relationship between their reactionrates and 1H or 13C NMR chemical shifts of unsaturated methylene groups was obtained from the kinetic studies.
环状烯酮缩醛与甲醇的反应以相当好的收率得到了相应的环状原乙酸酯。通过动力学研究获得了它们的反应速率与不饱和亚甲基的1 H或13 C NMR化学位移之间的线性关系。
