Application of a diastereoselective three-component coupling to the bicyclic core of the batzelladine alkaloids is described. The synthesis features the elaboration of glutamic acid by use of Eschenmoser sulfide contraction. An earlier approach is also included, which shows some limitations of dithiane chemistry when applied to the particular compounds required for this target.
该研究介绍了将非对映选择性三组分偶联法应用于巴泽拉定生物碱双环核心的情况。该合成的特点是利用埃申莫瑟硫化收缩法合成谷氨酸。此外还介绍了一种较早的方法,它显示了二噻烷化学在应用于该目标所需的特定化合物时的一些局限性。
