A general procedure for the asymmetric synthesis of 3-aryl-1,2,3,4-tetrahydroisoquinolines with any desired substitution pattern at both aromatic rings is reported. The methodology relies on the deoxygenation of 3-aryl-1,2,3,4-tetrahydroisoquinolin-4-ols 1a–e, which can be easily prepared from chiral non-racemic arylglycines under ionic hydrogenation conditions The target heterocycles are obtained
报道了在两个芳环上具有任何期望的取代模式的3-芳基-1,2,3,4-四氢异喹啉的不对称合成的一般方法。该方法依赖于3-芳基-1,2,3,4-四氢异喹啉-4-醇1a - e的脱氧,可以在离子氢化条件下由手性非外消旋芳基甘氨酸轻松制备。对映体纯的化合物。进一步的实验允许建立该通过S发生这种转化Ñ 1个机构,其中一个碳阳离子中间体物质首先形成并随后其经历与亲核氢化物载体,得到还原产物的快速反应。
