Microwave irradiation of 6-O-tosyl or 2,6-di-O-tosyl peracetylated hexopyranoses absorbed on basic alumina in a dry medium afforded the corresponding 1,6-anhydro-β-d-hexopyranoses. A direct access to 1,6:3,4-dianhydro-β-d-altropyranose (16) from d-glucose is also described.
微波辐照在干燥介质中的碱性氧化铝上吸收的 6-O-对甲基苯磺酰或 2,6-二-O-对甲基苯磺酰过乙酰化六吡喃糖,可得到相应的 1,6-脱水-δ²-d-六吡喃糖。此外,还介绍了从 d-葡萄糖直接获得 1,6:3,4-二氢-δ-d-阿洛托吡喃糖 (16) 的方法。
