SYNTHESIS OF (-) 4,8β-DIMETHYL TESTOLACTONE FROM (+) O-15-METHYL ISOAGATHATE

The stereoselective synthesis of (-) 4,8β-dimethyl testolactone 18 from (+) O-15-methyl isoagathate 7 is described.The construction of ring D by stereoselective electrophilic cyclization and the appropriate functionalization of the A-ring were carried out in a nine-step process with a good overall yield.
