  Long-chain (C(6) to C(16)) alkyl glucopyranosides have been synthesized using microwave irradiation. Yields and anomeric ratios can be controlled under precise and short irradiation times (few min). Comparison with classical heating showed a better efficiency of microwaves.

  长链（C（6）至C（16））烷基吡喃葡萄糖苷已使用微波辐射合成。可以在精确且短的照射时间（数分钟）内控制产率和异头比。与经典加热的比较表明，微波的效率更高。

  We have succeeded in developing a novel glycosidation catalyzed by a combination of trimethylsilyl bromide (TMSBr) and a Lewis acid using simple O-glycosides as glycosyl donors. Treatment of benzyl 2-deozy-2-tri-chloroethoxycarbonylamino-D-glucopyranoside with TMSBr and zinc bromide in the presence of glycosyl acceptors gave α-O-glycosides in moderate to high yields. Zinc triflate and tin(II)triflate were also found to be effective as the Lewis acid. This new methodology is applicable to methyl D-glucopyranoside.

  我们成功开发了一种新型的糖苷化反应，该反应是由三甲基氯化铵（TMSBr）和路易斯酸的组合催化，使用简单的O-糖苷作为糖苷供体。将苄基2-脱氧-2-三氯乙氧羧酰胺-D-葡萄糖吡喃糖苷与TMSBr和溴化锌在糖苷受体存在下处理，获得了中到高产率的α-O-糖苷。此外，三氟甲苯酸锌和亚锡三氟甲苯酸也被发现作为路易斯酸有效。该新方法适用于甲基D-葡萄糖吡喃糖苷。
