5-(4-Chlorophenyl)-7-(4-methylphenyl)-4-(pyrrolidin-1-yl)-7H-pyrrolo[2,3-d]pyrimidine
The title compound, C23H21ClN4, contains two molecules (A and B) in the asymmetric unit, which are related to one another by a pseudo-inversion center. The non-aromatic pyrrolidine ring in each independent mol-ecule adopts a half-chair conformation; the ring puckering parameters are θ = 0.407 (3) Å and ϕ = 270.5 (4)°, and the pseudo-rotation parameters are ρ = 72.5 (3)° and τ = 42.2 (2)° for an...
متن کاملMicrowave assisted synthesis of [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazine Derivatives
New pyrimido [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazines were synthesized via the cyclocondensation of alkyl-2-phenylhydrazinecarbodithioates as a binucleophile with 5-bromo-2,4-dichloro-6-methylpyrimidine as a bielectrophile , and replacement of C-7 chloro atom by hydrazine in ethanol as the solvent . This method has advantages over methods currently described in the literature for the con...
متن کامل(4-Chlorophenyl)(2-hydroxy-7-methoxynaphthalen-1-yl)methanone
The title compound, C(18)H(13)ClO(3), has an intra-molecular O-H⋯O=C hydrogen bond between the carbonyl group and the hydr-oxy substituent on the naphthalene ring system. The angle between the C=O bond plane and the naphthalene ring system is relatively small [20.96 (8)°]. The angle between the benzene ring and the carbonyl group is rather large [35.65 (9)°] compared to that in an analogous com...
متن کاملSynthesis and Leishmanicidal Activity of 1-[5-(5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl]-4-benzoylepiperazines
A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...
متن کامل(+)-[1-(4-Methoxybenzyl)pyrrolidin-2-yl]diphenylmethanol
The title compound, C(25)H(27)NO(2), was obtained as the product of a Grignard reagent and an inter-mediate ester synthesized from L-(-)-proline. The asymmetric unit contains two independent mol-ecules, both of which feature an intra-molecular O-H⋯N hydrogen bond. In one of the mol-ecules, the pyrrolidine ring is disordered over two orientations in a 0.63 (3):0.37 (3) ratio.
