Benzenediamine (233) and C-benzoyl-A -phenyl(thioformamide) (234) gave 2-anilino-3-phenylquinoxaline (235) (pyridime, reflux, 10 h 81%) or 3-phenyl-2(l//)-quinoxalinethione (236) (MeOH-AcOH, 20°C, N2, 3 days 46%) several analogs were made similarly. " ... [Pg.34]

The unsubstituted A-phenylbenzamide showed the most rapid hydrolysis. The introduction of a 4-N02 group (4.155) in the anilino moiety reduced the rate of hydrolysis twofold. The effect of a 2-C1 substituent (4.156) was similar. The compound with a 2-OH group in the benzoyl moiety (4.157) was hydrolyzed at a rate tenfold lower than that of the unsubstituted compound.

The syntheses shown in Scheme 26 (71CB1573) are based on dibenzo-/3-tropolone (108) and its enamines. Condensation of 108 and benzoin in the presence of ammonia affords pyrrole 109. The morpholino enamine gives pyrazole 110 via benzoylation, hydrolytic elimination of morpholine, and cyclization, whereas diazo-group transfer onto the anilino enamine leads to triazole 111. Dione 108 and p-nitrophenylazide in one step give predominantly the p-nitro derivative of 111 (92G249). [Pg.107]

Benzoyl-substituted anilino 1,1-enediamines 233 underwent oxidative cyclization with lead tetraacetate (LTA) to give iminoisoxazolines 235 in moderate yields183. In some cases, substituted indoles 236 were also formed. The formation of 235 and 236 has been assumed to arise through the initially formed JV-plumbylated adducts 234 (Scheme 14). [Pg.1357]

Benzoyl-anilino podophyllotoxin derivatives, (III), prepared by Kamal (2) and carbamate and thiocarbamate derivatives, (IV), prepared by Monneret (3), respectively, were effective against murine leukemia from L1210 cells. [Pg.600]

The only example of this system has been reported in a patent (83EGP156815). 5-Amino-l-benzoyl/substituted benzoyl-4-ethoxycarbo-nylpyrazolyl-3-thiones (72) react with either ethyl 3-anilino or substituted anilinocrotonates in boiling ethanol in the presence of metallic sodium to give 2-(a-anilino/substituted anilino)ethyl-5-benzoyl/substituted ben-...

Similarly, the 2-azidoethylene-l,l-dicarbonitriles (92) were found to react with aniline to give the corresponding anilino derivatives 121 Reaction of phenyl ethynyl ketone with sodium azide in an aqueous medium, it will be recalled, gave the isoxazole 74 (R = H). When this reaction was carried out in dimethylformamide, quite different results were found in this case the sodium salt of 4-benzoyl-1,2,3-triazole was isolated in good yield .

This type of approach constitutes a convenient synthesis of 5-functionalized thiazoles. 2,4-Diamino-S-acylthiazoles (292) can be prepared by reacting a-haloketones with alkyl- or aryl-3-amidinothioureas (290) in the presence of triethylamine <86S353> with iV-(anilino)benzylidenc-JV,iV -disubstituted thioiurcas (291), the reaction affords 2-amino-4-aryl-5-acyltWazoles (293). In contrast, the corresponding iV-benzoylthioureas (294) afford mainly 5-benzoyl derivatives (295)... [Pg.437]
