  Stereoselective synthesis of the C1–C12 subunit of (−)-callystatin A

  摘要：

  A stereoselective synthesis of the C1-C12 fragment of callystatin A is disclosed. The two stereocenters at C5 and C10 were created by an organocatalytic reaction and a diastereoselective alkylation, respectively. The trisubstituted double bond was introduced by a hydroxy directed hydrostannylation followed by the Negishi reaction. The lactone ring resulted from a ring-closing metathesis reaction.

  日期：——

  The total synthesis of the polyketide natural product callystatin A and its novel analog C19-epi-callystatin A is described. Our strategy features the use of an enantiomerically pure oxabicyclo[3.2.1]oct-6-ene as a template for the stereocontrolled preparation of the C15-C21 polypropionate region.
