Isomerization of 1, 4-Epoxy-1, 4-dihydronaphthalenes to 1-Naphthols by Activated Alumina

The Crystal Structure of a Photodimer of 1 , 4 - Epoxy - 1 , 4 - dihydronaphthalene

The crystal structure of a photodimer of l,4-epoxy-1,4-dihydronaphthalene, with empirical formula C20H1602, has been determined by the application of direct methods. Three-dimensional data were collected on a Datex-automated General Electric diffractometer to a minimum spacing of 1 ·0 A. The coordinates of all atoms in the molecule, the isotropic temperature factors for the hydrogen atoms, and ...

Synthesis and Leishmanicidal Activity of 1-[5-(5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl]-4-benzoylepiperazines

A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...

Dimethyl­ammonium 4-nitro­phenolate–4-nitro­phenol (1/1)

The title compound, C(2)H(8)N(+)·C(6)H(4)NO(3) (-)·C(6)H(5)NO(3), was synthesized from dimethyl-amine and 4-nitro-phenol in an overall yield of 85%. The dihdral angles between the nphenyl rings and their attached nitro groups are 5.7 (6) and 2.5 (7)°. In the crystal, there are strong hydrogen bonds between the ammonium group and the nitro-phenol and nitro-phenolate O atoms, and between the nitr...
