Nitrogenated heterocyclic compounds are present in both natural and synthetic drugs, and hexahydropyrimidine derivatives may prove to be efficient in treating dermatomycosis causing fungi. This study evaluated the antifungal activity of four hexahydropyrimidine derivatives against the dermatomycosis causing fungi. These derivatives were synthesized, characterized, and assessed in terms of their...

The title compound, C(15)H(17)N(3), was prepared by reaction of benzoyl-pyridine and hexahydropyrimidine. The 1,3-diazinane ring adopts a chair conformation with one N-H group axial and the other equatorial. The axial N-H group participates in very weak hydrogen bonding to the lone pair of electrons of the N atom with the equatorial H atom producing a very weakly hydrogen-bonded dimer. The pyri...

The reaction of ethyl benzoylacetate with formaldehyde and natural amino acid ester hydrochlorides in acetate buffer (AcONa/AcOH, pH 4.0) at room temperature afforded 41–61% new 5-benzoylhexahydropyrimidine derivatives. synthesized compounds were evaluated for their vitro cytotoxic activity against normal (HEK293) tumor cell lines (Jurkat, HepG2). T-Lymphoblastic leukemia Jurkat cells turned ou...

A relatively new entrant to the class of high energy materials, viz., 1,3,5-trinitro-5-methyl-hexahydropyrimidine (MTNP) has been synthesized during this work by nitration of 1,3-di-tert-butyl-5-nitro-5-methyl hexahydropyrimidine with fuming nitric acid. The synthesized molecule (MTNP) has been characterized by elemental analysis, IR, H and C NMR spectroscopy. TG of the compound showed two-step...

Two new hexahydropyrimidine compounds were prepared in high yield by condensation of an equimolar amount of 1,3-diamine with 2-dipyridylketone at room temperature in dichloromethane. The desired hexahydropyrimidine structures were confirmed on the basis of their UV-Visible, elemental analysis, FT-IR, 1H-NMR, TG/DTG, and EI-MS ...
