Novel multicomponent approach for the synthesis of 2,9-dihydro-2-oxo-4-aryl-1H-pyrido[2,3-b]indole-3-carbonitrile derivatives via 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 hydrogensulphate) has been reported.
for the one-pot synthesis of novel 2,9-dihydro-2-oxo-4-aryl-1H-pyrido[2,3-b]indole-3-carbonitrile derivatives by condensation of substituted (triethoxymethyl)arene, 1-methyl-1H-indol-2-ol and cyanoacetamide in the presence of a catalytic amount of crosslinked poly(2-acrylamido-2-methyl propane sulfonic acid) (AMPS) as an efficient and heterogeneous catalyst. This polymeric solid acid catalyst is stable
通过缩合缩合反应一锅法合成新的2,9-二氢-2-氧-4-芳基1 H-吡啶并[2,3 - b ]吲哚-3-腈衍生物。催化量的交联聚(2-丙烯酰胺基-2-甲基丙烷磺酸)(AMPS)的存在下,取代的(三乙氧基甲基)芳烃,1-甲基-1 H-吲哚-2-醇和氰基乙酰胺是一种高效且多相的催化剂。该聚合固体酸催化剂是稳定的,并且可以容易地回收和再利用而其活性没有明显变化。
A NOVEL METHOD OF PREPARATION FOR ORTHOCARBOXYLATES FROM DITHIOCARBOXYLATES AND DIALKOXYDIBUTYLSTANNANES
The reaction of methyl dithiocarboxylates with dialkoxydibutylstannanes at 60-95°C afforded the corresponding trialkyl orthocarboxylates in good yields.
