Treatment of the ozonization products from N-acetyl- or 2-methyl-N-trifluoroacetyl-6-(cyclopent-1-enyl)anilines with NaBH4 gives 6-methyl-2-tetrahydropyranylaniline. When treated with Me2S, the ozonization products yield the corresponding oxoaldehyde dimethyl acetals. The oxidation of N-acetyl-2-(cyclopent-1-enyl)- or -(cyclohex-1-enyl)anilines with H2O2 in HCOOH affords -(2-acetamidophenyl)-5-oxopentanoic or -6-oxohexanoic acid, respectively. The reaction of N-acetyl-2-(cyclopent-1-enyl)aniline with H2O2 in the presence of Na2WO4 and H3PO4 gives 3,1-benzooxazine in high yield. 相似文献

Cyclization of the N-methylimino derivatives in polyphosphoric acid gives 3,4-dihydroquinazolines in high yields. 相似文献

N-Acetyl-6-(cyclopent-1-enyl)-2-methylaniline underwent intramolecular cyclization in the presence of HCl in CH2Cl2 at 20°C to form 2,8-dimethylspiro[cyclopentane-1,4′-4′H-3,1-benzooxazine] in quantitative yield.

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.

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.

The molecular structures of various conformers of 2-hydroxy-1,4-naphthoquinone; 3-(alk-1-enyl)-2-hydroxy-1,4-naphthoquinones;
2,5,8-trihydroxy-1,4-naphthoquinone; and 3-(alk-1-enyl)-2,5,8-trihydroxy-1,4-naphthoquinones were studied by density functional
theory (B3LYP/6-31(d), B3LYP/6-31(d, p)) and ab initio (MP2/6-31G, MP2/6-31(d)) methods. The strengths of the intramolecular hydrogen bonds formed by the β-hydroxy group with the
O atom at C(1) and with the double bond π-electrons of the alkenyl substituents in the quinonoid rings were estimated. The
compounds studied mainly exist as rotamers with the former-type hydrogen bonds. The splitting of the quinonoid bands of the
stretching vibrations of the β-hydroxy group in the IR spectra of 3-(alk-1-enyl)-2-hydroxy-1,4-naphthoquinones and 3-(alk-1-enyl)-2,5,8-trihydroxy-1,4-naphthoquinones
in hexane solutions is due to the existence of rotamers formed upon internal rotation of the alkenyl substituent.

Substituted 3-(alk-1-enyl)-2-hydroxynaphthazarins were synthesized. According to data from IR spectroscopy, these compounds exist in organic aprotic solvents as mixtures of tautomeric 1,4-naphthoquinonoid forms. The compositions of tautomeric mixtures were quantitatively determined. The effects of the structure of the alkenyl substituent and the polarity of the solvent on the tautomeric equilibrium were qualitatively estimated.__________Published in Russian in Izvestiya Akademii Nauk.

2,4,6-Trichloro 1,3,5-triazine was selectively reacted with new nucleophilic reagents such as 4-methoxy-2-aminobenzothiazole, 2-chloro-4-trifluoromethyl-aniline, and phenylsubstituted thiourea in alkaline medium to give 2-(4-methoxybenzothiazol-2′-ylamino)-4-(phenylthioureido)-6-(substitutedthioureido)-1,3,5-triazines. The structures of these compounds were confirmed by IR, 1H NMR, 19F NMR, mass spectral data, and elemental analysis. The compounds show fungicidal activity against Alternaria alternata, Aspergillus niger, and Macrofomina. Supplemental materials are available for this article.

Ozonolysis of N-acyl-2-(1-methylbut-2-enyl)- and N-acyl-2-(cyclopent-2-enyl)anilines followed by treatment with NaBH4 afforded the corresponding 2-(2-hydroxyethyl-1-methyl) and 2-(1,5-dihydroxypent-2-yl) derivatives.

The reaction of 2-methyl-3-(4-tolyl)-4(3H)-quinazolone with benzil produces 2-[(Z)-3-oxo-2,3-diphenylprop-1-enyl]-3-(4-tolyl)-4(3H)-quinazolone, which is readily transformed into 2-(3,3-diphenylsuccinimido)-N-(4-tolyl)benzamide on dissolution in organic water-containing solvents. The rearrangement mechanism was suggested and investigated
by the quantum chemical PM3 method.
