Novel ways for preparing the title compounds have been developed. Saturated (1) and unsaturated (2) aldehydoesters, which are easily accessible by a Pd-catalyzed reaction of ethyl 4-bromobenzoate with methallyl alcohol and aldol condensation of ethyl 4-formyl-benzoate with propanal, respectively, are strategically advantageous intermediates for the synthesis. The results of thein vitro assays of some
已开发出制备标题化合物的新方法。饱和 (1) 和不饱和 (2) 醛酯,它们很容易通过 Pd 催化的 4-溴苯甲酸乙酯与甲烯丙醇的反应以及 4-甲酰基苯甲酸乙酯与丙醛的羟醛缩合反应而获得,它们是具有战略意义的中间体,可用于合成。将一些合成化合物的体外试验结果与其体内药理作用的已知数据进行比较。
