  Total Synthesis of Lathyranoic Acid A

  摘要：

  The first total synthesis of lathyranoic acid A (1) was accomplished stereoselectively in a linear sequence of 20 steps and an overall yield of 1.4%. This modular synthesis featured a cyclic, stereocontrolled Cu-catalyzed intramolecular cyclopropanation to construct the cis-cyclopropane unit, a Grubbs metathesis to construct the gamma-substituted cyclopentenone moiety, and an anion-mediated conjugate addition.
