An efficient and direct preparation of functionalized δ-carbolines, via a ring closure reaction between the appropriate indole amine and a masked 1,3-dicarbonyl compound is described. This method afforded new 3-substituted δ-carbolines and these products were subjected to ortho-lithiation experiments. Various 3,4-disubstituted δ-carbolines were obtained in acceptable yields.
描述了通过合适的吲哚胺与被掩蔽的1,3-二羰基化合物之间的闭环反应有效且直接地制备官能化的δ-咔啉的方法。该方法提供了新的3-取代的δ-咔啉,并且将这些产物进行邻位锂化实验。以可接受的产率获得了各种3,4-二取代的δ-咔啉。
