The title compound, C 28 H 41 NO 6 , was obtained by reduction of benzyl 2-deoxy-2-(3,5-di-tert-butylsalicylideneamino)--dglucopyranoside. The benzyl substituent is in an axial position, whereas the 3,5-di-tert-butylsalicylamino substituent and the hydroxyl groups are in equatorial positions. The en
This paper reports the polycondensation of benzyl 2-amino-2-deoxy-a-o-glucopyranoside hydrochloride (1) with carbon dioxide using the triphenylphosphine/carbon tetrachlorideDBU system as a condensing agent to give poly(urethane) (2). The polycondensation of 1 with COz was carried out in DMF solvent
In the crystal structure of the title compound, C 24 H 26 O 9 , molecules are linked by O-HÁ Á ÁO hydrogen bonds, creating a chain of hydrogen-bonded molecules in the c-axis direction.
Ethyl 2-amino-4,6-O-benzylidene-2-deoxy-D-gluconate adds to acetylenic esters to give sugar enaminones. The following acetylene derivatives have been employed: methyl propiolate, ethyl phenylpropiolate, and dimethyl acetylenedicarboxylate ( 6). With compound 6, the reaction leads to a mixture of th
