Treatment of methyl beta-lactoside with triphenylphosphine-carbon tetrabromide in pyridine gave the 3',6'-anhydro-6-bromo-6-deoxy derivative, from which 6-thio derivatives were prepared, and methyl 3',4'-O-isopropylidene-beta-lactoside gave the 6,6'-dibromo-6,6'-dideoxy derivative. A dibromide was prepared also from methyl 4',6'-O-benzylidene-beta-lactoside by bromination with Ph3P-CBr4, acetylation, and

The conformation in solution of methyl beta-galactopyranosyl-(1-->4)-alpha-glucopyranoside (methyl alpha-lactoside) and methyl beta-galactopyranosyl-(1-->6)-beta-glucopyranoside (methyl beta-allolactoside) has been studied through NMR spectroscopy and molecular mechanics calculations. NOE measurements both in the laboratory and rotating frames, have been interpreted in terms of an

Syntheses of the 3-aminodeoxy (4), 3-deoxy-3-methyl (5), and 3-epi (6) derivatives of methyl beta-lactoside (1) have been achieved from 1 in a straightforward way, and their solution conformations in water and dimethyl sulfoxide analysed through molecular mechanics and dynamics calculations
P Fernández et al.
Carbohydrate research, 248, 15-36 (1993-10-04)
The solution conformations of all the possible monomethyl ethers of methyl beta-lactoside have been analysed using molecular mechanics and dynamics calculations and nuclear magnetic resonance data (variable temperature and NOE experiments). The overall shape of all the compounds studied is
Hongqiu Zhao et al.
The Journal of organic chemistry, 72(19), 7071-7082 (2007-02-24)
Density functional theory (DFT) has been used to investigate the structural dependencies of NMR spin-coupling constants (J-couplings) involving the exchangeable hydroxyl protons of saccharides. 3JHCOH, 3JCCOH, and 2JCOH values were calculated at different positions in model aldopyranosyl rings as a
