The synthesis of a meso-2,3-dibenzylbutanedioic acid anhydride is given. Reaction of this with (+)-α-methylbenzylamine proceeds diastereoselectively to give a butanedioic acid monoamide which is converted into an enantiomerically enriched cis-2,3-dibenzylbutyrolactone lignan.
给出了内消旋-2,3-二苄基丁二酸酐的合成。该化合物与(+)-α-甲基苄基胺的反应非对映选择性地进行,得到丁二酸单酰胺,其转化为对映体富集的顺式-2,3-二苄基丁内酯木脂素。
