Transformations of o-nitroarylallyl carbanions. Synthesis of quinoline N-oxides and N-hydroxyindoles.
摘要:
Nitriles and esters of 2-(o-nitroaryl)crotonic acids are converted under basic conditions into substituted quinoline N-oxides, N-hydroxyindoles and N-hydroxy-2-hydroxymethyl indoles. Factors governing the reaction course and mechanistic pathways are discussed.
condensation of ortho-cyanomethylated nitroarenes with N-methylpyrrolidone, followed by cyclization promoted by O,N-bistrimethylsilylacetamide and DBU in DMF led directly to pyrrolo[3,2-b]quinoline derivatives.
