Monoacylation by use of lipase/trifluoroethyl butanoate systems occurred predominantly at the 2-position of methyl 6-O-butanoyl-a-D-glucopyranoside and at the 4-posidon of methyl 6-deoxy-a-L-glucopyranoside. Methyl 4,6-O-benzylidene-a- and - D-glucopyranoside were preferentially acetylated at 0-2 and 0-3, respectively, by lipase/vinyl acetate Exposure of the galacturono-6,1-lactone triacetate 32 (see Chapter 16 for its synthesis) to wheat germ lipase gave the diacetate 33 in modest yield. ... 

The effect of Q-alkylation on the anomeric solution equilibrium of D-glucopyranose and of methyl D-glucopyranoside has been studied. A considerable increase in the proportion of a-anomer for 2-Q-methyl-D-glucopyranose was observed, but there was no change for methyl D-glucopyranoside on Q-alkylation. A method has been reported for the preparation of all of the methyl ethers of methyl 2-acetamido-2-deoxy-a-D-glucopyranoside. Methylation of methyl (methyl o-D-mannopyranosid)uronate, methyl (methyl o-D-glucopyranosid)uronate, and methyl (methyl p-D-... 

Thin-layer Chromatography.— Improved or more-rapid separations by t.l.c. have been reported for mono-, di-, tri- and oligo-saccharides, naturally occurring pentitols and hexitols, iridoid D-glucopyranosides, methylated nucleosides, " and D-arabinosyl-, o-ribosyl-, and 2-deoxy-D-ery Aro-pentosyl-nucleotides.
