以L-α-氨基酸为起始原料, 经酯化、氨基保护、肼解制得N-对甲苯磺酰基-L-α-氨基酸酰肼2, 再与糖基异硫氰酸酯3～5反应, 得到9种新型N-糖基-N'-酰氨基硫脲6～8, 然后在Hg(OAc)2/EtOH条件下关环, 合成了一系列新的2-对甲苯磺酰氨基烃基-5-糖氨基-1,3,4-噁二唑类化合物9～11. 所有新化合物的结构均经IR, 1H NMR, MS谱和元素分析确证.

关键词: 氨基酸酰肼, 1,3,4-噁二唑, 糖基异硫氰酸酯, 酰氨基硫脲, L-α-氨基酸

The starting material L-α-amino acids were converted into N-p-toluenesulfonyl-L-α-amino acid hydrazides 2 through following steps, esterification, amino protection and hydrazinolysis. The reaction of 2 with glycosyl isothio-cyanates 3～5 gave the novel compounds, N-glycosyl-N'-amido thioureas 6～8. The compounds 6～8 were cyclized under the system of Hg(OAc)2/EtOH to afford a series of new compounds, 2- p-toluenesulfonylaminoalkyl-5-glycosylamino-1,3,4-oxadiazoles 9～11. The structures of the new compounds were confirmed by IR, 1H NMR, MS spectra and elemental analysis.

Key words: amino acid hydrazide, 1,3,4-oxadiazole, glycosyl isothiocyanate, amido thiourea, L-α-amino acid
