cyanohydrin nand the β γ-Unsaturated eater. The usefulness of the reagent is demonstrated by advantageous syntheses of the naturally occuring title-compounds and of various partially methylated analogues. The electron-donating substituents on the diene are disposed in order to illustrate the consequence of their oppossing electronic effects.
一种新的二烯,1,2-脱甲氧基-1-三甲基甲硅烷氧基-1,3-戊丁,是由巴豆醛经氰醇n和βγ-不饱和取代基制备的。通过天然存在的标题化合物和各种部分甲基化的类似物的有利合成证明了该试剂的有用性。布置二烯上的供电子取代基是为了说明它们相反的电子效应的结果。
