Abstract
d,l-Derrisic acid (IIa, R′: H) was synthesized from d,l-hydroxy dihydrotubanol (Ve) by Hoesch condensation with a nitrile (VI). The possible optical resolution of d,l-IIa was demonstrated by a conventional “reversed resolution” method.This communication and previous works constitute the first total synthesis of natural rotenone (Ia).
