  Total synthesis of dihydromevinolin and a series of related 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors

  摘要：

  The natural product dihydromevinolin, 2, and a series of structurally related 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, 3-6, have been synthesized. The key features are an intramolecular Diels-Alder reaction to form a functionalized decalin skeleton with six asymmetric centers in a stereocontrolled manner, the selective manipulation of the functional groups, and an improved method for the introduction and elaboration of the delta-lactone portion. Analogue 6 was approximately 10-fold more potent than 2 as an inhibitor and was produced in multigram quantities.
