perovskite particles as catalyst in methanol at 40 ºC gave the corresponding secondary amines in good to high yields....
Synthesis of new multi-functionalised 1,1’-carbonylbispyrazole derivatives
A new series of multi-functionalised 1,1’-carbonylbispyrazole derivatives were synthesised through cyclisation of pyrazole carbohydrazides with some substituted methylene malononitriles in very good yields. The structures ...
Nano-sized NiLa2O4 spinel–NaBH4-mediated reduction of imines to secondary amines
reaction times.
Secondary amines with different aryl groups, including those bearing electron-withdrawing or
electron-donating groups, were obtained under the optimum reaction conditions. The catalyst was
readily recovered...
Synthesis of a novel fused tricyclic heterocycle, pyrimido[5,4- e ][1,4]thiazepine, and its derivatives
Sequential treatment of 5-bromo-2,4-dichloro-
6-(chloromethyl)pyrimidine with 2-aminothiophenol
and secondary amines afforded a series of 2-[(5-bromo-
2-chloro-6-aminopyrimidin-4-yl)methylthio]aniline derivatives...
An alternative approach to the synthesis of new pyrimido[5′,4′:5,6][1,4] thiazino[2,3-b]quinoxaline derivatives
3-[(5-bromo-2-chloro-6-methylpyrimidin-4-yl)thio]quinoxalin-2-amine. This intermediate can be transformed into the title ring systems by subsequent treatment either with secondary amines followed by intramolecular cyclisation or initial...
