2-Methyl-2-(3-nitrophenyl)-1,3-dithiane
The title compound, C(11)H(13)NO(2)S(2), contains a 1,3-dithiane ring in an almost ideal chair conformation with the following puckering parameters: Q = 0.7252 (15) Å, θ = 6.71 (13) and ϕ = 50.4 (11)°. The benzene ring occupies an axial position at the dithiane ring. The nitro group is almost coplanar with the benzene ring [O-N-C-C = -3.2 (2)°]. The mol-ecule has an L-shape with a C-C-C-C torsi...
متن کامل2-(1,3-Dithian-2-yl)-1,3-dithiane-2-carbaldehyde
The asymmetric unit of the title compound, C(9)H(14)OS(4), comprises two crystallographically independent mol-ecules with similar conformations. In each mol-ecule, an intra-molecular C-H⋯O hydrogen bond generates a six-membered ring, producing an S(6) ring motif. All of the six-membered dithia-cyclo-hexane rings adopt chair conformations. The crystal structure is stabilized by four inter-molecu...

Quinolone antibacterials are one of the most important classes of pharmacological agents known as potent inhibitors of bacterial DNA gyrase and topoisomerase IV that efficiently inhibit DNA replication and transcription by generating several double-stranded DNA break. Some quinolone derivatives demonstrated inhibitory potential against eukaryote topoismarase II and substantial dose-dependent cy...
متن کاملFuran derivatives. ЬХХП. Synthesis and some properties of l-(5-nitro-2-furyl)- -2- (5-aryl-2-furyl)ethylenes
Wittig reaction has recently been applied also in the preparation of 5-nitrofuran derivatives of ethylene [1—5]. The quoted syntheses were accomplished starting either from 5-nitrofurfuryl halides which were converted into 5-nitrofurfurylidenephosphoranes and subsequent condensation of the latter with carbonyl compounds [1—4], or the intermediate phosphoranes were prepared from other furfuryl h...
