Practical synthesis of lespedezol A1

A practical formal synthesis of lespedezol A1 (1) was accomplished in 33% yield for four steps starting from formation of the substituted chalcone. Of particular note is a useful protocol for reduction of the 2-ene bond in the isoflavone intermediate. A significant improvement in the final ring closure when water was scavenged from the reaction is also noteworthy. The ready availability of lespedezol A1 will provide material for further pharmacological evaluation and for exploration of the pterocarpene nucleus as a potential entry into various 6a-hydroxypterocarpans.

A NEW ROUTE TO RESORCINOLS

A convenient preparation of resorcinol derivatives from α-phenylsulfinyllactones and α,β-unsaturated ketones is described.
