“…A D-galactose (1) e a lactose (2) foram submetidas à peracetilação e os derivados peracetilados (3 e 4) foram transformados nos brometos de glicosila correspondentes, 5 e 6 19,20 . Em seguida foram obtidos os intermediários 7 e 8, com rendimentos de 58 e 70%, respectivamente, pela substituição do bromo em C-1 pelo grupo azido 21,22 .…”

“…Uronic acid contents were measured by the raeta-hydroxydiphenyl method.4) * Present address: Faculty of Science of Living, Osaka City University, 3-3-138 Sugimoto-cho, Sumiyoshi-ku, Osaka 558, Japan. To examine the effects of the acetyl groups on Smith degradation, deacetylated mannan I-a, I-b, and I-c were prepared using freshly prepared sodium methoxide, 10) and then studied. The proportion of erythritol and glycerol increased while that of mannose decreasedextensively.…”

“…Tlie results in Table I show this expectation to be co~lfirmed. As anticipated, the molecular rotation cliffere~lce is significantl!, greater for a -and 0-forms of 3-plienoxy-4-oxa-5a-cholestane (+67g0); phenyl a-D-glycop~~ranosides generall3-differ fro111 phellyl 0-~-gl]rcopj.ranosides in molecular rotation by a b o~~t +GOO0 (6,7).According to these configurational assig~uiients, the isomer more strongly adsorbed 011 alumina is in every case tliat having an equatorial allcoxy group. This is in line with the effect on adsorl~tion of the configuratio~~ of the liydrox~.l groups of steroidal alcohols (8).…”
