The title synthesis could be accomplished by featuring the [2+2]-cycloaddition reaction of a chiral imine with benzyloxyketene, alcoholysis of the formed 2-azetidinone derivative, and reductive removal of the mandelate-derived benzylic oxygen by way of a 2-oxazolidone derivative.
可以通过特征在于手性亚胺与苄氧基烯酮的[2 + 2]-环加成反应,形成的2-氮杂环丁酮衍生物的醇解和通过2-恶唑烷酮还原去除扁桃酸衍生的苄基氧来完成标题合成。衍生物。
