Diastereoisomers of a new heterocyclic system, i.e. 1,2,3,4,6,7,9,10,15b,15c-decahydropyrido-[1″,2″:1′,2′]pyrazino[4′,3′:1,2]pyrido[3,4-b]indoles (7a) and (7b), as well as their 6- and 7-oxo derivatives (5a),(5b) and (2a),(2b), respectively, were synthesized. The structure of individual diastereoisomers was determined using 1H and 13C NMR techniques.
新杂环系统的非对映异构体,即1,2,3,4,6,7,9,10,15b,15c-十氢吡啶并-[1“,2”:1',2'] pyrazino [4',3' :1,2] pyrido [3,4- b ]吲哚(7a)和(7b)以及它们的6-和7-氧代衍生物(5a),(5b)和(2a),(2b) ,被合成。使用1 H和13 C NMR技术确定单个非对映异构体的结构。
