ring-expansion–glycosylation reaction was performed using 1,2-cyclopropanated sugars as glycosyl donors and carbohydrate O-nucleophiles as acceptors to provide septanohexose mimics of pyranose and furanose derivatives. The methodology was successfully extended to the synthesis of septano-oligosaccharides by adopting a divergent strategy as well as an iterative protocol.
使用1,2-环丙烷化的糖作为糖基供体,并使用碳水化合物O-亲核试剂作为受体,进行一锅扩环糖基化反应,以提供吡喃糖和呋喃糖衍生物的庚烷己糖模拟物。通过采用分歧策略和迭代方案,该方法成功地扩展到了庚烷低聚糖的合成。
