Tetrazoles remain a challenge to photochemists. Photolysis leads to cleavage of the
tetrazolyl ring, may involve various photodegradation pathways and may produce a diversity …

Quantum chemical calculations of geometries and vibrational wavenumbers of N-2 (methoxy
phenyl) acetamide (N2MPA) in the ground state were carried out by using density functional …

Tetrazoles exhibit a very rich photochemistry, strongly influenced by the nature of
substituents in the tetrazolic ring. Photolysis of representative tetrazoles trapped in a rigid …

Background The emergence and spread of Plasmodium falciparum resistance to artemisinin-
based combination therapy in Southeast Asia prompted the need to develop new …

Novel isoxazolines and isoxazoles of N-substituted saccharin derivatives are synthesized in
good yields by 1, 3-dipolar cycloaddition of N-allyl or propargyl N-substituted saccharin with …

The synthesis and characterization of novel benzisothiazole-tetrazolyl derivatives differing
on the spacer-group used for the linkage of two heterocycles are described. The application …
