6H-Pyrido[x′,y′ : 5,6]oxepino[3,2-b]indol-5-(12H)-ones (3) are efficiently converted by hot alcoholic base in air into the corresponding 5H-pyrido[x,y-b]-carbazole-5,11(6H)-diones (5).
6 H -Pyrido [ x ',y ':5,6] oxepino [3,2- b ] indol -5-(12 H)-ones(3)在空气中被热的醇基有效地转化为相应的5 H -吡啶并[ x,y - b ]-咔唑-5,11(6 H)-二酮(5)。
