  Synthesis of novel discodermolide analogues with modified hydrogen-bonding donor/acceptor sites

  摘要：

  A series of novel structural analogues of the potent microtubule-stabilizing anticancer agent discodermolide were synthesised, with modifications in the C16-C20 region to create new oxygenated H-bonding donor/acceptor sites for tubulin binding. By starting from an advanced C9-C24 intermediate, fully synthetic discodermolide analogues, incorporating either an additional hydroxyl group 3, an oxetane 4 or a cyclic carbonate 5, were obtained in 10 or 11 steps by using a versatile aldol construction of the C6-C7 bond.
