The invention relates to new compounds of formulae:
Wherein:
R1 and R2 can be independently H; a C1 to C6 alkyl including methyl, ethyl, propyl, butyl; aryl including phenyl, para-methoxyphenyl; or R1,R2 together with the carbon C-6 can be a cyclopentylidene or cyclohexylidene; each of these groups being substituted or not;
and R3 can be a C1 to C6 alkyl including methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl; or aryl including phenyl, methylphenyl, ethylphenyl, each of these groups being substituted or not.
The invention also relates to their method of manufacture and their use for the synthesis of Ara-N3, Kdo-N3 and 4eKdo-N3.
本发明涉及新的式化合物:
其中
R1 和 R2 可以独立地为 H;C1 至 C6 烷基,包括甲基、乙基、丙基、丁基;芳基,包括苯基、对
甲氧基苯基;或 R1、R2 连同碳 C-6 可以是环亚戊基或环亚己基;R3可以是C1至C6烷基,包括甲基、乙基、丙基、异丙基、丁基、异丁基、叔丁基、戊基;或芳基,包括苯基、甲基苯基、
乙基苯基,其中每个基团均被取代或未被取代。
本发明还涉及它们的制造方法及其在合成 Ara-N3、Kdo-N3 和 4eKdo-N3 中的用途。
