A practical synthetic route to enantiopure 5-substituted cis-decahydroquinolines has been developed, the key steps being a stereoselective cyclocondensation of 2-substituted 6-oxocyclohexenepropionates 2 with (R)-phenylglycinol, the stereoselective hydrogenation of the resulting unsaturated tricyclic lactams, and the stereoselective reductive cleavage of the oxazolidine ring.
已开发出对映体纯的5-取代的顺式-十氢喹啉的实用合成路线,关键步骤是2-取代的6-氧代环己烯丙酸酯2与(R)-苯基甘醇的立体选择性环缩合,所得不饱和三环内酰胺的立体选择性氢化,以及恶唑烷环的立体选择性还原裂解。
