2,2-diphenyl-1-(trifluoromethanesulphonyl)-hydrazyl was prepared by oxidation of the corresponding hydrazine, and is stable in solution. Its ESR spectrum is interpreted in terms of a larger coupling constant for the tricoordinated than for the dicoordinated nitrogen, and of proton coupling constants indicating non-equivalent phenyl groups. 相似文献

1-Morpholino-1-(phenylethynyl)cyclopentane and 1-morpholino-1-(phenylethynyl)cyclohexane were obtained by reactions of enamines, derivatives of cyclic ketones, with phenylacetylene in the presence of CuI. A scheme for catalysis by Cu(I) compounds with the intermediate formation of copper phenylacetylide and iminium salts was suggested.Translated fromIzvestiya Akademii Nauk.

Reactions of 1-(4-bromophenyl)-3-morpholino-2-phenylpropan-1-one with various Grignard compounds in diethyl ether gave a broad series of tertiary amino alcohols, 3-(4-bromophenyl)-1-morpholino-2-phenylalkan-3-ol hydrochlorides, that can be regarded as Trihexyphenidyl analogs. 相似文献

The reaction of Ru3(CO)12 with 2-methyl-3-morpholino-1-phenylprop-2-en-1-one (1) produced the Ru6(CO)16(μ4-η1:η1:η2:η2-PhC(O)-C(Me)=C)2 (2), Ru2O2(CO)4(η3-OC(Ph)C(Me)C(H)C(Me)2C(Ph))2 (3), and [Ru(CO)2(PhCO2)(O(CH2-CH2)2NH]2 (4) complexes, which were characterized by IR and NMR spectroscopy. The structures of the complexes were established by X-ray
diffraction. The formation of the complexes is accompanied by deamination of ligand 1. Complexes 2 and 3 bearing the vinyl ketone groups contain five-membered oxaruthenacycles and dihydropyran rings. Morpholine is not removed
from the reaction mixture and leads to the formation of complex 4.

The title compound 1-(3-amino-4-morpholino-1 H-indazole-1-carbonyl)-N-(4-fluorophenyl)cyclopropane-1-carboxamide was synthesized by the condensation of 1-[(4-fluorophenyl)carbamoyl]cyclopropane-1-carboxylic acid with 4-morpholino-1 H-indazol-3-amine. This intermediate was prepared from 2,6-difluorobenzonitrile by the condensation with morpholine and then cyclisation with hydrazine hydrate. The crystal structure of the title compound was determined to be of monoclinic system, space group P21/c with a = 10.4645(13), b = 17.368(2), c = 13.7220(13) ? and β = 21.446(7)°. In addition, the compound possesses distinct effective inhibition on the proliferation of HT-29, MKN-45, K562 and A549 cell lines. 相似文献

1-Alkoxy-2,2-bis(trifluoromethyl)aziridines containing an ester group in the position of the alkoxy substituent undergo nucleophilic substitution (ammonolysis and hydrolysis) with retention of the aziridine ring. The corresponding carboxylic acids, which were separated to give the antipodes with an optical purity of 95% through the diastereomeric salts with R- and S--phenylethylamine, were obtained.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1495–1500, November, 1980. 相似文献

2,2′-Bipyridine (2BPY) and hexahydroxybenzene (HHB) crystallize in a 2:1 ratio as a neutral molecular adduct, C6H6O6·2C10H8N2, in space group P with Z = 1 and with the HHB molecule lying on an inversion centre. HHB, of which this is the first single-crystal X-ray structure determination, forms O—H⃛O hydrogen-bonded chains parallel to the a axis, with O⃛O distances of 2.761 (1) and 2.782 (1) Å. O—H⃛N hydrogen bonds to the 2BPY molecules crosslink these chains, with O⃛N distances of 2.707 (1) and 2.735 (1) Å. 相似文献
