THE ACETONATION OF LACTOSE AND BENZYL β-LACTOSIDE WITH 2-METHOXYPROPENE

The acetonation of lactose with 2-methoxypropene afforded 4,6-O-isopropylidene lactose (2) and a diacetal which, after acetylation, gave an α,β-anomeric mixture of 1,2,6,3'-tetra-O-acetyl-3,2':4',6'-di-O-isopropylidene lactose (4).Acetonation of benzyl β-

4-O-beta-D-Galactopyranosyl-3-O-methyl-D-glucose: a new synthesis and application to the evaluation of intestinal lactase.

4-O-beta-D-Galactopyranosyl-3-O-methyl-D-glucose (1, 3-O-methyl-lactose) has been prepared from benzyl 2,6-di-O-benzyl-4-O-(2,6-di-O-benzyl-3, 4-O-isopropylidene-beta-D-galactopyranosyl)-beta-D-glucopyranoside (5) and from benzyl 2,6-di-O-benzyl-4-O-(2,3,
