Damavandi, Saman; Sandaroos, Reza published an article in 2013, the title of the article was Novel multicomponent synthesis of 2,9-dihydro-9-methyl-2-oxo-4-aryl-1H-pyrido[2,3-b]indole-3-carbonitrile compounds.Category: esters-buliding-blocks And the article contains the following content:
A multicomponent approach for the synthesis of 2,9-dihydro-2-oxo-4-aryl-1H-pyrido[2,3-b]indole-3-carbonitrile derivatives by a one-pot cyclocondensation reaction of substituted (triethoxymethyl)arene, 1-methyl-1H-indol-2-ol and cyanoacetamide in the presence of silica supported ionic liquid [pmim]HSO4[SiO2] (silica-supported 1-methyl-3-(triethoxysilylpropyl)imidazolium hydrogen sulfate) has been reported. The title compounds thus formed included 2,9-dihydro-9-methyl-2-oxo-4-phenyl-1H-pyrido[2,3-b]indole-3-carbonitrile (I) and related substances, such as 2,9-dihydro-9-methyl-4-(1-naphthalenyl)-2-oxo-1H-pyrido[2,3-b]indole-3-carbonitrile. The synthesis of the target compounds was achieved using ortho esters, such s (triethoxymethyl)benzene, (trimethoxymethyl)benzene, etc., as starting materials. The experimental process involved the reaction of (Trimethoxymethyl)benzene(cas: 707-07-3).Category: esters-buliding-blocks
