A convergent asymmetric synthesis of the calcium ionophore ionomycin has been achieved through a route that is outlined below. The four illustrated subunits, which comprise the c,-C,,-,, CI)-&r cI&22, and C=-C32 portions of ionomycin,
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.
