Crystal structures of (5RS)-(Z)-4-[5-(furan-2-yl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl]-4-oxobut-2-enoic acid and (5RS)-(Z)-4-[5-(furan-2-yl)-3-(thiophen-2-yl)-4,5-dihydro-1H-pyrazol-1-yl]-4-oxobut-2-enoic acid

The title compounds, C(17)H(14)N(2)O(4) (I) and C(15)H(12)N(2)O(4)S (II), possess very similar molecular geometries. In both molecules, the central 1,3,5-trisubstituted dihydropyrazole ring adopts an envelope conformation. The oxobutenoic acid fragment has an almost planar Z conformation [r.m.s...
