Birch reduction of homotyramines with a syn-β-amino alcohol unit followed by acid treatment of formed dihydroanisole derivatives gives polysubstituted enantiopure cis-decahydroquinolines. The stereoselectivity of the process differs if the hydroxyl group is free or protected. The procedure allows the synthesis of 7-oxodecahydroquinolines embodying four stereogenic centres with the same relative configuration
用homotyramines的伯奇还原顺随后形成dihydroanisole衍生物的酸处理-β-氨基醇单元给出取代对映体纯的顺式-decahydroquinolines。如果羟基是游离的或被保护的,则该方法的立体选择性是不同的。该程序可以合成7个氧代十二氢喹啉,它们包含四个立体生成中心,其相对构型与Lepadins F和G具有相同的相对构型。
