The intramolecular Diels-Alder reactions between acyclic dienes and α,β-unsaturated amides utilizing the internal coordination of the metal salts have been studied in detail. When the magnesium salts of N-(trans, trans-2,4-alkadienyl)-N-(2-hydroxyphenyl)acrylamide derivatives are employed, the intramolecular Diels-Alder reactions are remarkably accelerated and the corresponding cycloadducts are obtained

Both aryne 1,4-disubstitution and 1,2,4-trifunctionalization were accomplished from tertiary amines bearing a penta-2,4-dien-1-yl moiety. A remote diastereoselective [5,5]-sigmatropic rearrangement process was observed in aryne 1,2,4-trifunctionalization.

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.
