Reaction of the anhydride of a meso-2,3-dibenzylbutanedioic acid with (+)-α-methylbenzylamine proceeds diastereoselectively to give an acid-amide which can be converted into an enantiomerically enriched cis-2,3-dibenzylbutyrolactone.

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.
