In various conditions, dimerization of pentanedial-derived units gives rise to interesting skeletons, which are reminiscent of alkaloids known to be biosynthesized in Nature via lysine metabolism. The Royal Society of Chemistry 2010.
DIHYDROPYRAN DERIVATIVES. VI.* REACTION OF FUNCTIONAL DERIVATIVES OF 3,4-DIHYDROPYRAN WITH ALCOHOLS

The reaction of functional derivatives of 3,4-dihydropyran with alcohols and glycols in the presence of hydrochloric acid leads to acetals with various structures, formed both through addition of the alcohols to the double bond and through alcoholysis leading to opening of the dihydropyran ring with the formation of glutaraldehyde acetals.
Une voie d'acces aux alcoxy-5 trimethyl-4,4,7a hexahydro-3aα,4,5,6,7,7aα (3H)-benzofurannones-2

Starting from 2-methoxy (or ethoxy)-3,4-dihydro-2H-pyran, a series of four reactions allows to obtain a good yield of two 4-alcoxy-3,3-dimethyl-1-hydroxymethyl cyclohexenes which are converted to methylenecyclohexylacetic acids by different or sigmatropic reactions.These acids are cyclized at room temperature with concentrated sulfuric acid into bicyclic γ-lactones having a cis-junction.The stereospecificity of this reaction and the stability of the isomers obtained are discussed.
