The invention relates to a method of synthesis for a compound of formula (I),
wherein R is a heterocyclyl moiety and X1, X2, X3 and X4 are, independently of each other, protecting groups, which is appropriate for the synthesis of epothilone B and desoxyepothione B.

In connection with our studies of the total syntheses of epothilones we report our efforts on the syntheses of epothilone B using a macro-lactonization and a metathesis approach. Key reaction for the solution of the acyclic stereoselection is a stereoselective aldol reaction.
