Abstract

The first total synthesis of solidago alcohol (8) has been achieved in racemic form. The synthetic endeavor takes advantage of a facile and highly face-selective Diels-Alder cycloaddition reaction of cross-conjugated β-keto ester 3, readily accessible from 3-ethoxy-2-cyclohexenone, and trans-piperylene.
