ARYLHYDRAZONOETHANETHIOAMIDES -- AMINO GROUPS -- ACYLTHIOAMIDES
Аннотация: The acylation of arylhydrazonoethanethioamides containing primary amino group did not yield acylthioamides as expected. Surprisingly, the cyclic 5-acylimino-2,5-dihydro-1,2,3-thiadiazoles were obtained. The formation of thiadiazoles in this reaction was explained by the higher ability of arylhydrazono-N-acylthioacetamide intermediates to be oxidized comparing to their precursors. The presence of pseudobicyclic aromatic structure in the reaction product was a main factor favoring the formation of 1,2,3-thiadiazole ring

Аннотация: Reactions of 4-(4-fluorophenyl)-, 4-(4-trifluoromethoxyphenyl)-, 4-(3,4-difluorophenyl)-, 4-(4-trifluoromethylphenyl)-, 4-piperidino-, and 4-(3-pyridyl)thiosemicarbazides with esters gave the corresponding 3,4-disubstituted 4,5-dihydro-1H-1,2,4-triazole-5-thiones and their S-alkyl derivatives. Analogous reactions with methyl 2,2,3,3,4,4,5,5-octafluoropentanoate and 2,2,3,3,4,4,5,5-octafluoropentanenitrile afforded, respectively, the acylation and addition products.

Аннотация: Enantiomers of 2-methyl-6-nitro-1,2,3,4-tetrahydroquinoline have been obtained by kinetic resolution of racemic 2-methyl-1,2,3,4-tetrahydroquinoline in acylation with acyl chlorides of N-protected amino acids followed by regioselective nitration of the diastereoisomeric amides and acidic hydrolysis. The introduction of a trifluoroacetyl protecting group into the position 1 of the enantio pure nitro compound followed by the reduction led to (S)-6-amino-2-methyl-1-trifluoroacetyl-1,2,3,4-tetra-hydroquinoline in a high yield

Аннотация: The reaction of zinc enolates synthesized from 1-aryl-2,2-dibromoalkanones and zinc with 6-R-2-oxochromene-3-carboxylic acid N-benzylamide affords 8-R-9c-alkyl-1-aryl-2-benzyl-1-hydroxy-1,2,9b,9c-tetrahydro-5-oxa-2-aza-cyclopenta[2,3]cyclopropa[1,2-a]naphthalene-3,4-diones. Acylation of these compounds is accompanied by an unexpected rearrangement producing a sole geometrical isomer of 4?-alkyl-5?-aryl-1?-benzyl-3,4,2?,3?-tetrahydro-2,2?-dioxospiro[chroman-3,3?-pyrrol]-4-yl acetates

Аннотация: The acylative kinetic resolution of racemic 2-methyl-1,2,3,4-tetrahydroquinoline and 2,3-dihydro-3-methyl-4H-1,4-benzoxazine using acyl chlorides of N-phthaloyl-(S)-phenylalanine, N-phthaloyl-3-(4-nitrophenyl)-(S)-alanine and N-phthaloyl-O-methyl-(S)-tyrosine as chiral resolving agents has been carried out. It is shown that the effectiveness of an acylative kinetic resolution depends on the electronic effects of substituents in the phenyl fragment of the acylating agent and increases as the electron-donating properties of the para-substituent (OMe H NO2) in phenyl fragment of N-phthaloyl-3-aryl-(S)-alanyl chlorides increase; conducting the process at a reduced temperature also contributes to an enhancement of the kinetic resolution

5,11-DIHYDROINDOLO[3,2-B]CARBAZOLES -- 2-ARYLGLY-OXALS -- ACYLATION
Аннотация: An efficient approach for the double acetylation of 5,11-dihexyl- 6,12-di(hetero) aryl-substituted 5,11-dihydroindolo[3,2-b] carbazoles with acetic anhydride in the presence of boron trifluoride etherate has been developed, thus affording the corresponding 2,8-diacetyl derivatives in good yields. A similar acylation has been shown to occur by the reaction of anhydrides of other carboxylic acids. Oxidation of the obtained 2,8-diacetyl derivatives with selenium dioxide takes place on heating or under microwave irradiation, thus resulting in the formation of the corresponding 2,8-diglyoxals. The latter proved to react with aromatic o-diamines to afford new indolo[3,2-b] carbazoles bearing quinoxalinyl fragments at C-2 and C-8. Major optical properties of quinoxaline- containing indolo[3,2-b] carbazoles have been measured.
