β-苯甲基2:3-内醚-4:6-苯亚甲基-D-同侧醣配醣物(IV)由β-苯甲基D-葡萄糖配醣物經三步反应制得.它和苯甲醇钠的反应,与相应的α-甲基2:3-内醚-4:6-苯亚甲基-D-同侧醣配醣物相同,但析得的产物只有β-苯甲基2-苯甲基-4:6-苯亚甲基-D-2-异侧醣配醣物(V).以上的转化证明了配醣基的不同和构型的改变,至少在所研究的一个配醣物的结果来看,对于内醚环形成的构型是没有影响的.

β-Benzyl 2:3-anhydro-4:6-benzylidene-D-a,lloside(Ⅳ) has been prepared from β-benzyl D-glucoside.Its behaviour towards,sodium benzylate has been obserzred to follow the same course as the corresponding a-methyl analogue,for the expected product,β-benzyl 2-benzyl-4:6-benzylidene-D-altroside(Ⅴ),is isolated.These observations demonstrate that the alteration of the glycosidic group as well as its configuration does not,at least in the case of the above compound studied,interfer with the course of formation of the ethylene oxidertng.
