β-Galactosyl ceramides have been obtained in excellent yields and stereoselectivities by reacting disarmed glycosyl donors with stannyl ethers. The broad compatibility of stannyl ethers with various leaving groupâpromoter pairs is demonstrated.

Abstract The directglycosylation of ceramides in supercritical carbon dioxide (scCO2) successfully proceeded to produce β-glycolipids in high yield and with full stereoselectivity. The reaction is promoted by montmorillonite modified with a superacid (CF3SO3H). The value of this protocol was demonstrated in the efficientsynthesis of isoglobotrihexosylceramide (iGB3). The directglycosylation of ceramides
摘要 神经酰胺在超临界二氧化碳(scCO 2)中的直接糖基化成功地以高收率和完全的立体选择性进行生产β-糖脂。该反应通过用超强酸(CF 3 SO 3 H)改性的蒙脱石来促进。该协议的价值在异源三异己糖基神经酰胺(iGB3)的有效合成中得到了证明。 神经酰胺在超临界二氧化碳(scCO 2)中的直接糖基化成功地以高收率和完全的立体选择性进行生产β-糖脂。该反应通过用超强酸(CF 3 SO 3 H)改性的蒙脱石来促进。该协议的价值在异源三异己糖基神经酰胺(iGB3)的有效合成中得到了证明。
