Kinetically controlled reaction of 4.5 equiv. of 2-methoxypropene with some alkyl (Y-and /3-o-galactopyranosides gave the 2,3:4,6-di-O-isopropylidene derivatives in high yields @O--85%). With 2 equiv. of 2-methoxypropene, benzyl P-Dgalactopyranoside gave the 4,6-and the 3,4-monoacetals in the ratio

As part of a programme involving X-ray crystallographic studies" of cis-and tpuns-fused hexopyranosides, we now report on the crystal structures of methyl 2-~-methyl-~-D-glucop~anoside\* (11, which was obtained by debe~lidenation of methyl 4,~-O-benzyIidene-2-O-methyI-3-O-~-tolylsulfonyl-~-~-glucopy
Methyl 3-O-(3,6-anhydro-beta-D-galactopyranosyl)-alpha-D-galactopyranoside (3) and methyl 3,6-anhydro-4-O-beta-D-galactopyranosyl-alpha-D-galactopyranoside (4) have been synthesised stereoselectively using three coupling procedures. Acceptable yields were achieved using acetylated derivatives as don
The molecule is a derivative of the naturally occurring carbohydrate D-fNCtOSe. The data reported here indicate that the ketose six-membered ring is constrained by the presence of two fused five-membered rings into the 3So conformation. These findings agree with the n.m.r.-spectroscopic results for
