1) Guanidinoglucoside
胍基糖苷
1.
Synthesis and Biological Activities of Novel Guanidinoglucosides;
将2,3,4,6-四-O-乙酰基-β-D-吡喃葡萄糖基异硫氰酸酯(1)与2-氨基-4/6-取代-苯并噻唑(2a~2e)反应,生成糖基硫脲衍生物(3a~3e),再在伯胺存在下经氯化汞脱硫,得到一系列新的多乙酰基胍基糖苷类化合物(4a~4d,5a~5d,6a~6d,7a~7d),糖基的保护基团在甲醇钠/甲醇条件下脱除。
2) guanidinoxylopyranoside
胍基木吡喃糖苷
1.
The reaction of 2,3,4-tri-O-acetyl-β-D-xylopyranosyl isothiocyanate 1 and 2-amino-4/6-substituted benzothiazoles 2a~2e gave xylopyranosylthioureas 3a~3e,which then reacted with alkyl/aryl amine in the presence of HgCl_2 to afford a series of new guanidinoxylopyranosides (4a~4e,5a~5e,6a~6e and 7a~7e).
2,3,4-三-O-乙酰基-β-D-木吡喃糖基异硫氰酸酯1与2-氨基-4/6-取代-苯并噻唑2a~2e反应,生成糖基硫脲衍生物3a~3e,再在伯胺存在下经氯化汞脱硫,得到一系列新的胍基木吡喃糖苷类化合物4a~4e,5a~5e,6a~6e,7a~7e,所有新化合物的结构均经IR,~1H NMR,MS谱和元素分析证实,所得产物均为β-构型。
3) lactosylguanidine
乳糖基胍
1.
The reaction of 2,3,6,2',3',4',6'-hepta-O-acetyl-β-lactosyl isothiocyanate (1) with 2-amino-4/6-substituted benzothiazoles 2a-2e gave lactosylthioureas 3a-3e, which were treated with amines in the presence of HgCl2 to afford a series of novel N-alkyl/aryl-N'-(4/6-substituted benzothiazol-2-yl)-N''-perace-tylated lactosylguanidines 4-6.
然后,在CH3ONa/CH3OH作用下,脱乙酰基得含苯并噻唑基的乳糖基胍类化合物7~9。
