The first total synthesis of the potent glycosidase inhibitors 1-O-β-d-glucopyranosyl-5-deoxyadenophorine and its aglycon congener is described in respectively 13 steps (9% overall yield) and 9 steps (29% overall yield) from (R)-Garner aldehyde. The synthesis takes advantage of several key reactions including a diastereoselective allylation of a chiral imine, a stereoselective epoxidation, and a glycoside
有效的糖苷酶抑制剂1- O - β - d-吡喃葡萄糖基-5-脱氧腺苷及其配子同源物的第一个总合成分别由(R)-加纳醛。该合成利用了几个关键反应,包括手性亚胺的非对映选择性烯丙基化,立体选择性环氧化和糖苷偶联。此外,这项研究明确地确定了天然产物的绝对构型。
