An organocatalytic tandem conjugate addition / intramolecular cyclization of malononitrile and conformationally restricted 1,4-dien-3-ones has been developed. A series of cinchona alkaloids and their derivatives were examined as the catalysts. Quinine was

MCM-41-SO3H, an ordered mesoporous silica material in which MCM-41 with covalently anchored sulfonic acid groups was used as an acidic catalyst for the rapid and 'green' synthesis of pyrano[3,2-c]pyridine derivatives under solvent-free conditions. Reusability of the catalyst, high yields, short reaction times, simplicity and easy workup are advantages of this novel synthetic procedure compared to the conventional methods reported in the literature.
Organocatalytic conjugate addition of malononitrile to conformationally restricted dienones
Hu, Zhi-Peng,Lou, Chun-Liang,Wang, Jin-Jia,Chen, Chun-Xia,Yan, Ming
experimental part, p. 3797 - 3804 (2011/07/08)
Organocatalytic conjugate addition of malononitrile to conformationally restricted dienones has been studied. A series of chiral primary and tertiary amine catalysts were screened. A piperidine-based thiourea-tertiary amine was found to be the efficient c
An atom efficient, solvent-free, green synthesis and antimycobacterial evaluation of 2-amino-6-methyl-4-aryl-8-[(E)-arylmethylidene]-5,6,7,8-tetrahydro-4H-pyrano[3,2-c]pyridine-3-carbonitriles
