Chitosan-TiO2 shaped as macroporous aerogels, lamellar cryogels or electrospun films act synergistically as acid-base bifunctional catalysts. Depending on the topology of the material, a marked difference in the selectivity for nitroaldol condensation is observed. the Partner Organisations 2014.
Mechanisms underlying the vasorelaxant effect of trans-4-methoxy-β-nitrostyrene in the rat mesenteric resistance arteries

Mechanisms underlying the vasorelaxant effects of the synthetic nitro compound, trans-4-methoxy-β-nitrostyrene (T4MN) were studied in isolated small resistance arteries from spontaneously hypertensive rats (SHRs). T4MN caused vasorelaxation in endothelium
Soluble guanylate cyclase stimulator, trans-4-methoxy-β-nitrostyrene, has a beneficial effect in monocrotaline-induced pulmonary arterial hypertension in rats

The soluble guanylate cyclase (sGC)/GMPc pathway plays an important role in controlling pulmonary arterial hypertension (PAH). We investigated whether the novel sGC stimulator trans-4-methoxy-β-nitrostyrene (T4MN), ameliorates monocrotaline (MCT)-induced

A metal-free, mild and chemodivergent transformation involving nitroalkanes has been developed. Under optimized reaction conditions, in the presence of trichlorosilane and a tertiary amine, aliphatic nitroalkanes were selectively converted into amines or nitriles. Furthermore, when chiral β-substituted nitro compounds were reacted, the stereochemical integrity of the stereocenter was maintained and α-functionalized nitriles were obtained with no loss of enantiomeric excess. The methodology was successfully applied to the synthesis of chiral β-cyano esters, α-aryl alkylnitriles, and TBS-protected cyanohydrins, including direct precursors of four active pharmaceutical ingredients (ibuprofen, tembamide, aegeline and denopamine).
Dipolar HCP materials as alternatives to DMF solvent for azide-based synthesis
Bai, Rongxian,Gao, Feng,Gu, Yanlong,Li, Minghao

Hypercrosslinked polymers HCP-DMF and HCP-DMF-SO3H containing abundant and flexible DMF moieties were designed and synthesized. Benefitting from the solvation microenvironment provided by the pseudo-DMF moities, the polar HCPs manifested outstanding performances in the conversions of NaN3 to benzylic azides and 1,2,3-triazoles in EtOH (95%), respectively, avoiding the use of risky DMF and improving the separation processes of the products.
