Sceletium A-4, a pyridine alkaloid isolated from the Sceletium species, has been synthesized for the first time in an enantiocontrolled manner along with (–)-mesembrine, an alkaloid isolated from the same plant, starting from a chiral cyclohexadienone synthon to determine the absolute configuration.
从蛇床子属植物中分离出的一种吡啶生物碱--蛇床子素 A-4,与从同一种植物中分离出的一种生物碱 (-)-mesembrine 首次以对映体控制的方式进行了合成,从手性环己二烯酮合成物开始,确定了绝对构型。
