Abstract
The construction of the C1-C10 lactone core of rhizoxin, a 16-membered anti tumoral macrolide, is reported. The strategy is based on the installation o f the C7 and C8 asymmetric centers with a Brown allylation reaction. The C5 asymmetric carbon was controlled during a lactonisation step, leading to t he equatorial chain at C5. Homologation sequences at C3 and C9 were perform ed via a Wadsworth-Emmons and a Takai reaction, respectively.
