Stereoselective total syntheses of two novel conformationally restrained epothiloneanalogues are described. Evans asymmetric alkylation, Brown allylation, and a diastereoselective aldol reaction served as the key steps in the stereoselective synthesis of one of the two key fragments of the convergent synthetic approach. Enzyme resolution was employed to obtain the second fragment as a single enantiomer
Epothilone analogues include a molecular scaffold which holds at least one segment of epothilone in a predetermined orientation and which rigidities a region between the macrolactone ring and the aromatic side-chain.

A method for synthesizing anti-leukemic epothilone analogues includes rigidifying a region between the macrolactone ring and the aromatic side-chain. The anti-leukemic compositions are non-naturally occurring epothilone analogue that are rigidified between the macrolactone ring and the aromatic side-chain.
