The title compound, C30H34N2O9 (4), is a product of the Michael reaction of azacrown ether with dimethyl acetylenedicarboxylate modified by an addition of NH3 (aq.) at 298 K. The aza-14-crown-4-ether ring adopts a bowl conformation. The dihedral angle between the planes of the benzene rings fused to the aza-14-crown-4-ether moiety is 8.65 (5)°. The tetrahydropyridine ring has a boat conformation. The molecular conformation is supported by one N—H⋯O and two C—H⋯O intramolecular hydrogen bonds. Both heterocyclic and amino N atoms have essentially planar configurations (sums of the bond angles are 359.35 and 358.00°). Compound 4 crystallizes as a racemate consisting of enantiomeric pairs of the 1R,21S diastereomer. In the crystal, molecules of 4 are connected by N—H⋯O hydrogen bonds, forming chains along . According to the PASS program (computer prediction of biological activities), compound 4 may exhibit antiallergic (72% probability) and antiasthmatic (67%) activity, as well as be a membrane permeability inhibitor (65%).

This article presents new research on income-based child indicators for immigrant children from 17 different national backgrounds and children of parents born in Sweden observed during the 3-year periods 1983-85, 1995-97 and 2008-10. This research examines mean household income, representation at the top of the income distribution and relative poverty differ for immigrant children from the corresponding levels among children with native born parents. Most of the analysis is concentrated on the second generation of immigrant children. It is shown that the relative position of immigrant children deteriorated between 1983-85 and 1995-97 when the labour market situation of immigrant parents weakened more than among native born parents. Changes thereafter were more complex. Children born in Sweden to parents from Denmark, Norway or Germany were as likely as children of native born parents to be observed at the top of the income distribution in contrast to children of parents from countries with middle or low human development. Poverty rates among immigrant children were higher among all categories of immigrant children in 2008-10 than among children of native born parents. These cross origin differences in income-based child indicators can be attributed to the reasons and qualifications parents had when they entered Sweden and the number of years since their immigration. A majority of children living in Sweden that are classified as poor in 2008-10 were immigrant children of various categories.

In the title compound, C27H19N3O4, the phenol and pyrazole rings are almost coplanar [dihedral angle = 0.95 (12)°] due to an intramolecular O—H⋯N hydrogen bond, whereas the phenyl ring is tilted by 40.81 (7)° with respect to the plane of the pyrazole ring. The aromatic ring with a nitrophenoxy substituent makes a dihedral angle of 54.10 (7)° with the pyrazole ring.
