We report a general method for the synthesis of the substituted 6H-pyrido[2′,3′:5,6] [1,3]oxazino[3,4-a]indole ring system (structure 1) via the cyclization from an indoline precursor with aldehydes or ketones followed by oxidative re-aromatization.
我们报告了一种一般的方法,用于通过取代基的环化反应合成取代的6 H-吡啶基[2',3':5,6] [1,3]恶嗪基[3,4- a ]吲哚环系统(结构1)带有醛或酮的二氢吲哚前体,然后进行氧化再芳构化。
