The novel racemic secondary alcohol (±)-2-{[4-(4-bromophenyl)-5-phenyl-4H-1,2,4-triazol-3-yl]sulfanyl}-1-phenyl-1-ethanol (12) has been successfully synthesized through S-alkylation of 4-(4-bromophenyl)-5-phenyl-4H-1,2,4-triazole-3-thiol (10) in alkaline medium with 2-bromo-1-phenylethanone followed by reduction the corresponding ketone 11. All compounds were characterized IR, 1D (1H, 13C, DEPT...

In the title compound, C(9)H(8)N(2), a mirror plane lies perpendicular to the phenyl and imidazole rings and passes through the bridging C-C bond, so that the imidazole ring is disordered over two sites about the mirror plane with the equal site occupancy; the asymmetric unit contains one half-mol-ecule. In the crystal, adjacent mol-ecules are linked via N-H⋯N hydrogen bonds.

One pot synthesis of terpyrromethanes (3a) and [di(1H-pyrrol-2-yl)methyl]heteroarenes (3b-m) has been delineated by Amberlyst 15 catalyzed condensation of pyrrole and heterocyclic aldehydes (2), not reported earlier. The compounds 3a and 3b have been formylated to 5-[di(5-formyl-1H-pyrrol-2-yl)methyl]-1H-pyrrole-2-carbaldehyde (4a) and 5[(5-formyl-1H-pyrrol-2-yl)(3-pyridinyl)methyl]-1H-pyrrole-...

Quinoline based new Schiff bases were synthesized from 3-Actyl 4-Hydroxy Quinolin-2-(1H)-one and screened their antibacterial antifungal activity. The 4-hydroxy-3-(1-((4-picolin-2-yl)imino)ethyl)quinolin-2-(1H)-one(L1),4-hydroxy-3-(1-((5-picolin-2-yl)imino)ethyl)quinolin-2(1H)-one(L2),4-hydroxy-3-(1-((6-picolin-2-yl)-imino)ethyl)quinolin-2(1H)-one(L3) 4-hydroxy-3-(1-((3-nitro-4-picolin-2-yl)imi...

Novel scaffolds are of uttermost importance for the discovery of functional material. Three different heterocyclic scaffolds easily accessible from isocyanoacetaldehyde dimethylacetal 1 by multicomponent reaction (MCR) are described. They can be efficiently synthesized by a Ugi tetrazole multicomponent reaction of 1. We discuss the synthesis, 3D structures, and other physicochemical properties.

The coordination of 2-pyridyltetrazolate and ortho-xylene-linked bis(NHC)cyclophane to Pt(II) yielded a novel complex characterised by enhanced pure deep-blue emission, whose intensity can be modulated via methylation of the tetrazole ring.

An improved method of the synthesis of flavanones catalyzed by pyrrolidine and BF(3) ·Et(2) O has been developed and a lot of flavanones could be easily synthesized via this method. The asymmetric synthesis of flavanone from benzaldehyde and 5-fluoro-2-hydroxyacetophenone has been studied and flavanone with moderate enantioselectivity was obtained in one step.
