A practical formal synthesis of lespedezol A(1) (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 A, will provide material for further pharmacological evaluation and for exploration of the pterocarpene nucleus as a potential entry into various 6a-hydroxypterocarpans.

A series of michellamine structural analogues was prepared in which the tetrahydroisoquinoline rings were substituted with a variety of simple aromatic ring systems. Additionally, the methyl groups on the central bis-naphthalene cores were replaced with hydrogen and methoxy. All the analogues were devoid of anti-HIV activity, suggesting that the heterocyclic portion of the tetrahydroisoquinoline ring is crucial for biological activity. (C) 1997 Elsevier Science Ltd.
