Abstract: O-cyclialkylation of substituted bis[3-hydroxy-2-(pyrimidin-2-yl)-2H-pyrazol-4-yl]methane by α,ω-dibromoalkanes with a hydrocarbon chain length of up to three CH2 groups has been carried out. A novel pyrazolophane, 1,6-dioxacycloundecane with symmetrically annulated fragments of 1-(pyrimidin-2-yl)-1H-pyrazole, was isolated and characterized… read more here.
