- Sm-Catalyzed Synthesis and Biological Activity of Acyclic and Cyclic Azadiperoxides
-
Acyclic diaminodiperoxides and cyclic azadiperoxides are synthesized by the reaction of 1,1-bis-(hydroperoxy)cycloalkanes with formaldehyde and primary arylamines in the presence of Sm-containing catalysts [SmCl3·6H2O, Sm(NO3/s

- Task-specific ionic liquid-mediated facile synthesis of 1,3,5 triaryltriazines by cyclotrimerization of imines and their biological evaluation
-
A highly efficient method for the synthesis of fluorinated 1,3,5-triaryltriazine derivatives is developed by the condensation reaction of aromatic amines and formaldehyde followed by spontaneous cyclotrimerization using task-specific 1,1,3,3-tetramethylguanidine trifluoroacetate [TMG][Tfa] ionic liquid as a environmentally benign solvent in excellent yields at room temperature. The synthesized compounds were subjected for in vitro antitubercular activity against Mycobacterium tuberculosis H37Rv strain using the LoewensteinJensen medium.

- Revisitation of Formaldehyde Aniline Condensation. VII. 1,3,5-Triarylhexahydro-sym-triazines and 1,3,5,7-Tetraaryl-1,3,5,7-tetrazocines from Aromatic Amines and Paraformaldehyde
-
A product study of the reaction between a number of aromatic amines substituted with widely different groups and paraformaldehyde in inert solvents was performed and found to yield 1,3,5-triaryl-1,3,5-hexahydrotriazines, 1,3,5,7-tetraaryl-1,3,5,7-tetrazocines and formaminals.It was not possible to correlate the product outcomes with the actual structure of the amine substrate.The X-ray diffraction structural determination of 1,3,5-tri-(t-butylphenyl)- (1b) and 1,3,5-tri-(m-fluorophenyl)-1,3,5-hexahydrotriazine (1c) showed the diaxial arrangement of the N-substituents.
