The convergent total synthesis of hypermodified epothilone analogs 1 and 2 has been achieved with the stereoselective cyclopropanation of allylic alcohol 17 and ring-closing olefin metathesis with diene 22 as the key steps. In spite of significant structural differences between these analogs and the natural epothilone scaffold, 1 and 2 are potent inducers of tubulin polymerization and inhibit the growth of human cancer cells in vitro with sub-nM IC50 values.

Compounds of formula (I), and their pharmaceutically acceptable salts and solvates, wherein X represents -O-, -NH-, -S-, -NHC(=O)- or -NHC(=S)-; R1 represents -H or a hydrocarbon chain; R2 represents -H, alkoxy, amino, a hydrocarbon chain or a radical of a cycle; R3 represents -H, a hydrocarbon chain or a radical of a cycle; R4 represents -H or a hydrocarbon chain; alternatively R3 and R4 form together a cycle; R5 and R6 represent -H or halogen, and R7 represents -H, a hydrocarbon chain or heteroaryl, are useful against bacterial infections in animals, including humans.
