Product 1

HCID 540215301-(6-Tetrahydropyranyloxyhexyl)-1-hydroxymethylcyclopent-3-ene

Procedure

The above procedure was repeated except that methyl cyclopent-3-ene carboxylate (prepared as described by A. H. Schmid and A. W. Wolkoff, J. Org. Chem. 32, 254 (1967)) was used with the 6-tetrahydropyranyloxyhexyl bromide of part D of this example and 1-(6-tetrahydropyranyloxyhexyl)-1-hydroxymethylcyclopent-3-ene was obtained as an oil (IR 3400, 3010 cm-1, nmr τ 4.4, 5.4, 6.35, 7.8, 8.5).
