Reactions with Ac2O/Py of sodium nitronate salts derived from primary or secondary nitroalkanes bearing hydroxyl groups at γ or more remote positions have been studied. In all cases, the results could be explained through an acetic nitronic anhydride intermediate, whose evolution depends on conformational factors, and also on the type of the hydroxyl group.
已经研究了由γ或更远的位置带有羟基的伯或仲硝基烷烃衍生的亚硝酸钠盐与Ac 2 O / Py的反应。在所有情况下,结果都可以通过乙酸乙酸酐中间体来解释,该中间体的演变取决于构象因素,还取决于羟基的类型。
Preparation of d-galactofuranosyl nitromethanes: a revision and a new approach
treatment then provides 76% of D-galactofuranosyl nitromethanes and finally results in the equilibrium of 77% of beta-D-galactopyranosyl nitromethane and 7-9% of three other tautomeric D-galactosyl nitromethanes. Thermal treatment of 7-deoxy-7-nitro-L-glycero-L-galacto-heptitol in boiling water peaks at a 58% content of D-galactofuranosyl nitromethanes and ends in a similar equilibrium mixture of four

A conserved inner-core oligosaccharide epitope expressed on the lipopolysaccharide (LPS) of a range of disease causing pathogenic bacterial isolates, including
Actinobacillus pleuropneumoniae
(Ap),
Mannheimia haemolytica
(Mh) and
Pasteurella multocida
(Pm), is disclosed. Construction of a mutant bacterial strain exclusively expressing the conserved inner core OS epitope as a terminally exposed structure has allowed the identification, production and isolation of an inner core LPS which is common to all three organisms. Further provided are associated vaccines, antibodies raised against the conserved LPS inner core and glycoconjugates comprising the LPS inner core linked to an immunogenic carrier.
