β,β-Disubstituted-1,3-dinitro compounds were obtained exclusively with an overall yield of 83% through a domino nitroaldol/elimination/1,4-addition process, when excess nitromethane was added to cyclohexanone or butanone using DBU (1,8-diazabicyclo[5.4.0]undec-7-ene), as basic catalyst. On the other hand, β-nitroalcohols could be in 30-84% yield, reacts different aliphatic ketones stoichiometri...

It is generally held that adenosine 3',5'-cyclic monophosphate (cAMP) mediates smooth muscle relaxation by the activation of cAMPdependent protein kinase (PKA). This hypothesis was tested in two intact smooth muscle preparations, the rat vas deferens and the bovine coronary artery, using exogenously applied cAMP and cAMP analogs. After 30 minutes of incubation, /V 6 ,2'-0-dibutyryl-cAMP (dBu-cA...

Single crystals of tris(2,3,4,6,7,8,9,10-octahydropyrimido[1,2- a ]azepin-1-ium) tri-μ 2 -iodido-bis[triiodidobismuth(III)], (C 9 H 17 N ) 3 [Bi I ], were prepared by solvothermal method, heating mixture BiI , KI, 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and ethanol at 443 K for six days. The asymmetric unit the title compound, which crystallizes in monoclinic space group P 1 / c contains one ]...

The wood polysaccharide composition, a new analytical method, based on ionic liquid dissolution of low amount biomass coupled with an ELISA essay polysaccharides. In the present work, we synthesized and tested several imidazolium 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) ILs for their ability to solubilize Douglas-fir while preserving wall polymer integrity. couple times-temperatures have been e...
