Synthesis of oxazino[4,3-a]indoles by domino addition-cyclization reactions of (1H-indol-2-yl)methanols and vinyl selenones in the presence of 18-crown-6
Herein we report the synthesis of biologically relevant oxazino[4,3-a]indoles by an environmentally friendly Michael addition-cyclization cascade using potassium hydroxide in dichloromethane employing variously substituted vinyl selenones and (1H-indol-2yl)methanols. The addition of 18-crown-6, as a complexing agent, is crucial to achieve high chemo- and regio-selectivity.
在这里,我们报道了通过使用各种取代的乙烯基硒酮和(1 H-吲哚-2基)甲醇的氢氧化钾在二氯甲烷中的环境友好的迈克尔加成环化级联反应,通过环境友好的迈克尔加成环化级联反应合成生物相关的恶嗪[4,3- a ]吲哚。 添加18-crown-6作为络合剂对于实现高化学和区域选择性至关重要。

Indole and azaindole compounds useful for the treatment of solid tumours and tumours of the blood are described, they being particularly effective in the treatment of drug resistant tumours; these compounds are also able to synergistically enhance the activity of known antitumour drugs. They can hence be used either alone as antitumour agents or in association with known antitumour drugs. Processes for preparing the aforesaid compounds, which are partly new, and pharmaceutical compositions useful for the aforesaid treatments are also described.
