SYNTHESIS OF AN OPTICALLY ACTIVE 13β-METHYL 14β-HYDROXY STEROID VIA BASE-CATALYZED REACTIONS

The synthesis of optically active 14β-hydroxy steroid 9 is reported.This steroid is obtained in only two steps from chiral precursors 6 and 7 via anionic cycloaddition followed by base-catalyzed aldol reaction of tricetone 8.
