One-Pot Synthesis of 3-Oxocycloalka[c]pyridines

Abstract: A new efficient one-pot procedure has been developed for the synthesis of 1-substituted partially hydrogenated 3-oxocycloalka[c]pyridine-4-carbonitriles by reaction of cyclopentanone or cyclohexanone with morpholine, acyl chloride, and cyanoacetamide. The proposed procedure is advantageous due to shorter reaction time and smaller amounts of the solvents and reactants.

Synthesis and characterization of new long-wavelength-absorbing oxonol dyes from the 2,2-difluoro-1,3,2-dioxaborine type

By starting from methyl- and methylene-substituted 2,2-difluoro-1,3,2-dioxaborines 5, 20, and 21 and different types of reactive formyl derivatives (14-17) a series of anionic, cationic, and betainic methine dyes has been prepared. These dioxaborine dyes
