Development of a Scalable Synthesis of a Common Eastern Tricyclic Lactone for Construction of the Nodulisporic Acids
摘要:
A scalable, second-generation synthesis of the densely functionalized eastern tricyclic lactone (+)-6, a common intermediate, for construction of the nodulisporic acids has been achieved. Modifications to the first-generation route now permit access to (+)-6 in 17 steps with an overall 16.5% yield. Key carbon-carbon bond constructions include a Kirk-Petrow (phenylthio)methylation, a Sc(OTf)(3)-catalyzed hydroxymethylation, a Stille carbonylation, and a Koga three-component, conjugate addition-alkylation sequence.

As a continuation of the recently communicated discovery of oximinoarylsulfonamides as potent inhibitors of HIV-1 aspartyl protease, compounds bearing pyridylmethyl substituents at P3 were designed and synthesized. Potent analogs in this series provided low single-digit nanomolar EC50 values against both wild-type HIV and resistant mutant virus (A17), attenuated some 3- to 12-fold in the presence of
