Propargyl amines 4, where R(3) is aryl, undergo 5-exo-dig cyclization reactions under relatively mild conditions (AgNO(3), DMF, 60 °C, 1 h) to give 3-amino-2,3-dihydro-2-arylmethylidenebenzofurans 5 (R(3) = aryl). In contrast, substrates where R(3) is alkyl undergo competing 6-endo-dig and 5-exo-dig cyclization processes. The hydroxymethyl substrate 4 (R(3) = CH(2)OH), however, was smoothly con...

Some pharmacologically active sulpha/substituted Indoles were synthesised by refluxing the mixture of sulpha/substituted phenyl amine and α-haloacyl benzene in glacial acetic acid. The newly synthesised compounds were characterised by IR, 1H NMR, and UV spectral studies. They were also evaluated for their promising pharmacological activity such as anti-tuberculosis and anti-inflammatory activit...

The reduction of a partially deprotonated bishydroxylamine complex {(Bu2Ga)2[cyclo-ON(Me)(CH2)2(Me)NO][HON(Me)(CH2)2(Me)(H)NO]} with a reagent composed of titanium tetrachloride and methyllithium leads to the reduction of one of the N–O groups to an amine function affording the salt {(Bu2Ga)[cycloON(H)(Me)(CH2)2NHMe]} {tBu2GaCl2}−. This has been characterised by 1H and 13C NMR spectroscopy, by ...

The structures of two zinc complexes containing bidentate benzene-1,2-di-amine ligands are reported. (Benzene-1,2-di-amine-κ(2) N,N')di-chloro-idozinc, [ZnCl2(C6H8N2)], (I), displays a distorted tetra-hedral coordination sphere for the metal cation. The di-amine ligand and the Zn atom reside on a crystallographic mirror plane. In the 1:1 co-crystal salt trans-di-aqua-bis-(4,5-di-methyl-benzene-...

The crystal structure of the title salt, [Cu(ClO4)(C8H20N4)]ClO4, is reported. The CuII ion exhibits a square-pyramidal geometry and is coordinated by the four N atoms of the neutral 1,4,7,10-tetra-aza-cyclo-dodecane (cyclen) ligand and an O atom from one perchlorate anion, with the second perchlorate ion hydrogen-bonded to one of the amine N atoms of the cyclen ligand. Additional N-H⋯O hydroge...

The title compound {systematic name: 4-[bis(4-fluorophenyl)methyl]piperazin-1-ium 2,4,6-tri-nitro-phenolate}, C(17)H(19)F(2)N(2) (+)·C(6)H(2)N(3)O(7) (-), is the picrate salt of a piperazine-supported amine bearing a benzhydryl substituent on one of its N atoms. During co-crystallisation, protonation took place on the N atom of the secondary amine functionality. The non-aromatic six-membered he...

background: acute lymphoblastic leukemia (all) is the most common form of childhood cancer leading to cancer-related death in children. most infants with all harbor recurring structural chromosomal rearrangements that are important initiating events in leukemogenesis but are insufficient to explain the biology and heterogeneity of the disease. mixed-lineage leukemia-rearrangement (mll-rearrange...

The title 1:1 stoichiometric salt, C7H10N(+)·C7H13O2 (-), is formed by proton transfer between hepta-noic acid and benzyl-amine. This combination contrasts to the recently published 2:1 acid-amine adduct of cation, anion and neutral acid molecule from the same components [Wood & Clarke (2013 ▶). Acta Cryst. E69, o346-o347]. There are N-H⋯O hydrogen bonds of moderate strength in the structure [t...

Abstract Auxinic herbicides have been commonly used in production systems for broadleaf weed control many years. One potential negative aspect to their use is propensity volatilize and move away from the treated area after application. This research examined three herbicide formulations relative amounts of vaporization following application under field conditions Knoxville, TN, 2017, 2018, 2019...
