Synthesis of isoflavonoids. Enantiopure cis- and trans-6a-hydroxypterocarpans and a racemic trans-pterocarpan

Aldol condensation between phenylacetates and benzaldehydes affords 2,3-diaryl-3-hydroxypropanoates which serve as common precursors to both the first racemic trans-pterocarpan and enantiopure cis- and trans-6a-hydroxypterocarpans.

The first direct synthesis of pterocarpans via aldol condensation of phenylacetates with benzaldehydes

Aldol condensation between phenylacetates and benzaldehydes affords 2,3- diaryl-3-hydroxypropanoates which are converted into pt pans in moderate to high yields.
