Starting from 4-substituted cyclohexanones, a practical synthetic route to enantiopure 6-substituted cis-decahydroquinolines has been developed, the key steps being a stereoselective cyclocondensation of an unsaturated δ-keto ester derivative with (R)-phenylglycinol and the stereoselective hydrogenation of the resulting tricyclic oxazoloquinolone lactams.
从4-取代的环己酮开始,已开发出对映体纯的6-取代的顺式-十氢喹啉的实用合成路线,关键步骤是不饱和δ-酮酯衍生物与(R)-苯基甘醇的立体选择性环缩合以及对苯二酚的立体选择性氢化。生成三环恶唑喹诺酮内酰胺。
