high-yielding synthesis of dEpoF. The reduction of the keto group at C3 via a Noyori protocol after Suzuki coupling had proved to be very difficult. In our current approach, two consecutive aldol reactions are used to fashion the acyl sector. In the first aldol condensation, C6 becomes attached to C7. Following protection at C7, a two-carbon acetate equivalent is used to join C2 and C3 with very high asymmetric

The invention relates to a novel process for the preparation of an epothilone derivative of the formula (I) wherein R1 and R2 are silyl protecting groups, that uses a sultam alcohol of the formula (IV) wherein R is hydrogen or lower alkyl and R1 is a silyl protecting group, as intermediate. The compound of formula (I) is useful for the preparation of desoxyepothilones that are promising candidates for novel anticancer agents.
