Synthesis of the tetrahydropyran fragment of bistramide D

A synthesis of the tetrahydropyran (THP) moiety of bistramide D has been completed by using cross-metathesis and kinetically controlled intramolecular oxa-Michael addition to form the ring with excellent trans selectivity. The C9 methyl substituent was introduced by using an unsaturated sulfone buil...

description A synthesis of the tetrahydropyran (THP) moiety of bistramide D has been completed by using cross-metathesis and kinetically controlled intramolecular oxa-Michael addition to form the ring with excellent trans selectivity. The C9 methyl substituent was introduced by using an unsaturated sulfone building block, which can be most effectively prepared through a combination of diastereoselective allylation and alkene isomerisation. The effect of this methyl group on subsequent cross-metathesis reactions can be mitigated by careful choice of reaction conditions.
