New procedure was developed for preparation of the fragment C10-C21 of epothilone D analog from R-(-)-carvone. The key stage of the synthesis consists in the regio- and stereoselective Wittig reaction of (5R)-5-acetyl-2-methylcyclohex-2-en-1-one with an ylide generated from tributyl[(2-methylthiazol-4-yl)methyl]-phosphoniumchloride.
