A procedure was developed for synthesis of polycyclic pyrimidine derivatives by the reaction of 2,2'-dichlorodicyclohexyl sulfide with uracil, 6-methyluracil, or 5-fluorouracil in the presence of K2CO3, followed by oxidation of the resulting products with sodium metaperiodate and hydrogen peroxide. Two of the synthesized compounds were tested in extraction of Ir(IV) from hydrochloric acid solutions. 相似文献

Oxidation of 2′-hydroxy-8-methylspiro[4H-benz-1,3-oxazin-2-one-6,1′-cyclopentane] or N-mesyl-2-(cyclopent-1-en-1-yl)-6-methylaniline provided the corresponding ketones. The rearrangement of these ketones oximes under treatment with thionyl chloride gave rise to nitriles of 5-(2-amino-3-methylphenyl)-5-oxopentanoic or 5-(2-methanesulfamido-3-methylphenyl)-5-hydroxypentanoic acids. By heating 5-(2-acetylamido-3-methylphenyl)-5-oxopentanoic acid with LiH in THF3-(2,8-dimethylquinol-4-on-3-yl)propanoic acid was obtained. 相似文献

Intramolecular cyclization ofo-alkenylanilines was studied. Heating ofo-(cyclopent-2-en-1-yl) arylammonium chlorides at 200–220 °C yields cyclopenta[b]indolines as the main reaction products. Cyclization of 4-methyl-2-(pent-3-en-2-yl)aniline under the same conditions gave
a mixture of indolines and tetrahydroquinolines. An alk-1-enylarylamine containing a vinylic double bond does not form cyclization
products on the nitrogen atom.

R. R. Gataullin T. V. Kazhanova F. F. Minnigulov A. A. Fatykhov L. V. Spirikhin I. B. Abdrakhmanov 《Russian Chemical Bulletin》2000,49(10):1767-1770
When reacting with I2, 2-(cyclopent-2-enyl)anilines undergo cyclization into 3-iodo-1,2,3,3a,4,8b-hexahydrocyclopenta[b]indoles in high yields. The minor reaction products were 3,5- or 3,7-diiodoindolines. Ammonolysis of 3-iodo-5-methyl-1,2,3,3a,4,8b-hexahydro-cyclopenta[b]indole or itsN-chloroacetyl derivative results in 3-amino-5-methyl-1,2,3,3a,48b-hexahydro- and 5-methyl-1,3a,4,8b-tetrahydrocyclopenta[b]indoles.

Condensation of 2-[(E)-pent-3-en-2-yl]-4-, 2-[(E)-pent-2-en-2-yl]-4-, or 2-(cyclopent-1-enyl)-6-methylaniline with 1-chloro-1-(N-methylimino)- or 1-chloro-1-(N-phenylimino)ethane affords the corresponding amidines. Cyclization of the N-methylimino derivatives in polyphosphoric acid gives 3,4-dihydroquinazolines in high yields. 相似文献

The cyclization has been studied of N-(2-cyclopent-1-en-1-ylphenyl)benzamides into the corresponding 3,1-benzoxazines by the
action of gaseous hydrogen chloride, trifluoroacetic acid, or bromine, and also under conditions of electron impact in the
gas phase. A scheme is proposed for the fragmentation of the molecular ions of the products obtained. 相似文献
