The first stereoselective total synthesis of the natural cryptopyranmoscatone B1 has been accomplished from 3,4,6-tri-O-acetyl-d-glucal. In addition to the double cross-metathesis reaction, a tandem nucleophilic addition-diastereoselective reduction of an in situ generated oxocarbenium cation have been used as key steps to assemble the glycoside moiety of the target molecule.
自然cryptopyranmoscatone B1的第1立体选择性全合成已经从3,4,6-三完成ö乙酰基d -glucal。除了双重交叉复分解反应,原位产生的氧碳鎓阳离子的串联亲核加成-非对映选择性还原已被用作组装靶分子糖苷部分的关键步骤。
