Concise syntheses of (−)-habiterpenol and (+)-2,3-epi-habiterpenol via redox radical cyclization of alkenylsilane

Abstract

The concise syntheses of (–)-habiterpenol and (+)-2,3-epihabiterpenol from (3aR)-(+)-sclareolide and 6-methoxyindanone in 11 and 12 steps, respectively, were enabled by the regioselective addition of the TMS-indenyl anion and the facile...
