Use of [hydroxy(tosyloxy)iodo]benzene in a novel and facile synthesis of 1,4-diaryl-2-(arylamino)but-2-ene-1,4-diones

The reaction of acetophenones 1 with [hydroxy(tosyloxy)iodo]benzene followed by treatment of the resulting α-tosyloxyacetophenones 2 thus formed with anilines 3 in the presence of sodium carbonate in ethanol provides a novel one-pot synthesis of 1,4-diary

Transition-metal-free solid phase synthesis of 1,2-disubstituted 4-quinolones via the regiospecific synthesis of enaminones

Herein, the transition-metal-free economical solid phase synthesis of 1,2-disubstituted 4-quinolones has been developed via the novel regiospecific synthesis of enaminones. Notably, a wide range of enaminones were synthesized via a silica-supported solid-

Tribenzoyldihydropyridinols from dibenzoylacetylene and imines

The reaction of dibenzoylacetylene with N,N′-dialkyl or N,N′-diaryl glyoxal-bisimnes or with benzylideneanilines in boiling ethanol leads to the formation of pentasubstituted 1,2-dihydropyridines in 52-87% yield together with the corresponding enamines derived from dibenzoylacetylene.

Thermal Reactivity of Tricyclic 4,5-Diacyltriazolines Resulting from Addition of Aryl Azides to 1,4-Naphthoquinone and 2-Methyl-1,4-naphthoquinone

Reaction of 4-methoxyphenyl azide 1a with 1,4-naphthoquinone 10 at 15-100 deg C in benzene, dimethyl sulphoxide, or nitromethane leads mainly to the ring-contracted enamine 18a, the ring-expanded 2-benzazepine-1,5-dione 20a, and the aziridine 16a, the decomposition products of an intermediate triazoline 12a, to an extent largely independent of the solvent polarity and the temperature employed.However, the triazole 15a appears to be the main decomposition product of the triazoline 12a produced in hexamethylphosphoric triamide.A comparable chemical trend is observed with thermal additions of 4-nitrophenyl azide 1b to the quinone 10.Cycloaddition of the azide 1a to 2-methyl-1,4-naphthoquinone 11 leads regioselectively to the formation of the triazoline adduct 13a, which undergoes preferential isomerization to an isolable diazo dione 23a.On the other hand the azide 1b leads to a mixture of the regioisomeric triazolines 13b and 14b.The triazoline 13b, analogously to 13a, rearranges to the ring-opened diazo dione 23b, whereas the triazoline 14b is converted into a mixture of the ring-contracted and ring-expanded products 24b and 21b.The possible reaction mechanisms involved in the decomposition of the triazolines 12a and 12b, 13a and 13b and 14b are discussed.

Reactions of aromatic nitro compounds with acetophenone in the presence of alkali. Crystal structure of (E)-1,2-dibenzoyl-o-tolylaminoethylene

Methyl and methoxy substituted nitroarenes were reacted with acethophenone in the presence of sodium ethoxide in ethanol giving arylamino-conjugated diketo derivatives.A case of ipso-substitution of a methoxy group is discussed.The title compound C23H19NO
