Synthetic Studies on Spirovetivane Phytoalexins. IV. A Stereoselective Synthesis of (+/-)-3-Hydroxysolavetivone

Oxidation of the silyl enol ether of (2RS,5RS,10RS)-6,10-dimethyl-2-pivaloyloxyspirodec-6-en-8-one (5) with triphenyl phosphite ozonide (TPPO) gave stereoselectively the C9-hydroxylated derivative (6a), which was transformed into a spirove
