The synthesis of a number of novel simplified eleutheside analogues with potent tubulin-assembling and microtubulestabilizing properties is described, using ring-closing metathesis as the key-step for obtaining the 6-10 fused bicyclic ring system. (C) 2003 Elsevier Science Ltd. All rights reserved.
Synthesis of novel simplified sarcodictyin/eleutherobin analogs with potent microtubule-stabilizing activity, using ring closing metathesis as the key-step
The synthesis of a number of novel simplified eleutheside analogs with potent tubulin-assembling and microtubule-stabilizing properties is described, using ring closing metathesis as the key-step for obtaining the 6–10 fused bicyclic ring system. The RCM precursors were synthesized starting from aldehyde 3 [prepared in 6 steps on a multigram scale from R-(−)-carvone in 30% overall yield] via multiple
