glycosylation of unprotected d-xylose and d-lyxose, obtained after tandem Mo(VI)-catalyzed xylan hydrolysis-epimerization reaction, provides alkyl xylosides and lyxosides in short reaction times. A homologous series of amphiphilic alkyl pentosides varying in chain structure (C8-C14) was prepared in very good yields (38-73%). A new catalytic approach using the reusable heterogeneous PMoA/SiO2 catalyst provides
微波辅助的磷钼酸(PMoA)催化的,未经保护的d-木糖和d-木糖的串联糖基化反应,是在Mo(VI)催化的木聚糖水解-表观电子化反应后获得的,可在较短的反应时间内提供烷基木糖苷和lyxosides。以非常好的收率(38-73%)制备了一系列在链结构上不同的两亲烷基戊糖苷的同源序列(C8-C14)。使用可重复使用的非均相PMoA / SiO2催化剂的新催化方法在产量,环境安全性,操作简便性方面均具有优势,从而为合理利用半纤维素生物质开辟了新视野。
