本文报道利用1-O-三氟乙酰基-2,3,4,6-四-O-苄基-α-D-吡喃葡萄糖或吡喃型甘露糖在Lewis酸催化下合成α-硫苷的新方法。反应条件温和,产率高,并且具有很高的立体选择性。通过元素分析、IR并根据~1H NMR ~(13)C NMR确定了硫苷化合物的构型。
This paper reports the synthesis of α-glucoside using 1-O-trifluoroacetyl-2,3,4,6-tetra-O-benzyl-α-D-glucopyranose or mannopyrande The new method The reaction conditions are mild, high yield and high stereoselectivity. The configuration of the glucosinolate was confirmed by elemental analysis, IR and 1H NMR ~ (13) C NMR.
