In the title salt, {(C(10)H(11)N(3))[V(4)O(8)(PO(4))(2)]}(n), cubane-like [V(4)O(8)](4+) clusters are connected by phosphate anions into anionic [V(4)P(2)O(16)](n) (2n-) layers. These aggregate into the three-dimensional structure via N-H⋯O hydrogen-bonding mechanisms imparted by 4,4'-imino-dipyridinium dications situated between the layers.

The title compound, 2-{2-[1,3-di-tert-butyl-4-(tert-butyl-amino)-2-(tert-butyl-imino)-1,3,2λ(5),4-diaza-diphosphetidin-2-yl]-1-(4-meth-oxy-phen-yl)prop-2-en-1-yl}-5,5-dimethyl-1,3,2λ(5)-dioxaphosphinan-2-one, C(31)H(57)N(4)O(4)P(3), was synthesized from the Phospha-Michael addition reaction of cyclo-diphos-pha-zane [(t-BuNH)P(μ-Nt-Bu)](2) and allenyl-phospho-nate [(OCH(2)C(CH(3))(2)CH(2)O)P(O)C...

In the crystal structure, the title Schiff base compound, C(23)H(30)N(2)O(4), exhibits crystallographic twofold rotation symmetry. The imino group is coplanar with the aromatic ring with an N-C-C-C torsion angle of -179.72 (9)°. An intra-molecular O-H⋯N hydrogen bond forms a six-membered ring, producing an S(6) ring motif. The dihedral angle between symmetry related benzene rings is 28.05 (5)°....

The facile synthesis of a resorcin[4]arene-based imino-cavitand with benzamido moieties and its self-assembly into molecular capsules are reported. Benzamido-iminocavitand efficiently self-assembled into thermally inert molecular capsules in the presence of suitable guests via the eight intermolecular N-H···O=C hydrogen bonds.

A sequential three-component process is described, starting from 3-arylmethylene-2,5-piperazinediones and involving a one-pot sequence of reactions achieving regioselective opening of the 2,5-diketopiperazine ring and diastereoselective generation of an aziridine ring. This method allows the preparation of N-unprotected, trisubstituted aziridines bearing a peptide side chain under mild conditio...

It had long been thought, but never demonstrated, that imino acids are formed in the reactions catalyzed by D- and L-amino acid oxidases (EC 1.4.3.3 and 1.4.3.2). The formation of imino acids is now shown directly by allowing the amino acid oxidase reaction to proceed in the presence of NaBH(4), when the imino acid is reduced to the corresponding racemic amino acid. Thus, when NaBH(4) is added ...

Chalcone and their heterocycalic analogues are known to posses a broad spectram of biological effects. The present study is devoted to the synthesis of 6-bromo-4-methoxy-4-(substituted phenyl) imino flavones. The newly synthesized compounds were screened for their antimicrobial and antifungal activities. 2-hydroxy-5-bromo-4-methoxychalconeimine on refluxing in DMSO for two hrs in presence of ca...
