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