Abstract Isopropylidenation of lactose with 2, 2-dimethoxypropane in N, N-dimethyl- formamide at 80-85 gave a 1: 2 mixture of the kinetically favored 4′, 6′-acetal 1 and the thermodynamically more-stable 3′, 4′-acetal 2, which were separated by chromatography. The 1, 2, 3, 6, 2′, 6′-hexaacetate (3) and the 1, 2, 3, 6, 2′, 6′- hexabenzoate (4) of 2, as well as the corresponding, deacetonated esters 5 and 6, were ...
