A stereoselective 10-step synthesis of the fungalmetabolite (+)-decarestrictine L from commercially available ethyl (R)-3-hydroxybutyrate is described in which tandem oxonium ylide formation and rearrangement is used to construct the tetrahydropyranyl core of the natural product.
A stereoselective synthesis of (+/-)-decarestrictine L (1) from protected pentane-1,4-diol (2) is described. The key intermediate, tetrahydropyran-3-one 5a, was obtained by a tandem intramolecular carbenoid insertion and ylide rearrangement reaction.
