The conjugate additions of a variety of organocopper reagents or dimethyl malonate anion to a spirocyclic cyclopent-2-enone connecting a 1,2:5,6-di-O-isopropylidene-α-D-glucofuranosyl ring as a constituent of the spiro structure, namely (1S,3R,4R,5R)-3,4-(isopropylidenedioxy)-1-[(1R)-1,2-(isopropylidenedioxy)ethyl]-2-oxa-spiro[4.4]non-6-en-8-one, proceeded stereoselectively in some cases affording a variety of β-functionalized cyclopentanone derivatives. The thermal treatment of (1S,3R,4R,5R)-7-(hydroxymethyl)-3,4-(isopropylidenedioxy)-1-[(1R)-1,2-(isopropylidenedioxy)ethyl]-2-oxaspiro[4.4]non-6-ene, another D-glucose-derived spirocyclic substrate, with triethyl orthoacetate in the presence of a catalytic amount of acid afforded the Claisen rearrangement product with a high level of diastereoselectivity.
