A rapid synthetic approach to natural meso-nordihydroguaiaretic acid (NDGA) and its non-meso isomer is described from (3,4-dimethoxyphenyl)acetone using as a key step the low-valent Ti-induced carbonyl-coupling reaction of the ketone. The method involves a simple separation of the E- and Z-isomers that result from the dehydroxylation of the diol product of the coupling. The present approach allows
从(3,4-二甲氧基苯基)丙酮描述了一种快速合成天然内消旋-去氢二氢愈创木酸(NDGA)及其非内消旋异构体的方法,该方法以低价钛诱导的酮的羰基偶联反应为关键步骤。该方法涉及由于偶联的二醇产物的脱羟基作用而导致的E-和Z-异构体的简单分离。本方法允许制备NDGA的各种类似物。
