SYNTHESES, ANTIFUNGAL AND ANTIBACTERIAL ACTIVITIES OF SUBSTITUTED 1,2, CTRIMOLES
The reaction of readily available 1 -methyl-4-nitropyrrole-2- carboxylic acid (1) with thionyl chloride afforded the corresponding acyl chloride 2. The reaction of compound 2 with thiosemicarbazides yielded 1-(1 -methyl-4-nitrop yrrole-2-carbony1)- thiosemicarbazides (3) which cyclized in basic medium to 5-(1-methyl-4-nitropyrrole- 2-y1)-2,4-dihydro-3H- l,2,4-triazole-3- thione 4. Alkylatio...
متن کاملSyntheses of highly functionalised 6-substituted pteridines.
Methods for the synthesis of polyfunctional 6-substituted pteridines from the corresponding 6-aldehydes are described. Alkene, ester, ketone, amide, cyano, oxime, bromo, methoxy and dihydroxy functional groups have all been introduced principally through improved methodologies for Wittig reactions using 2-thioalkyl-6-formylpteridines as substrates. Further modification of the alkenes derived fr...
متن کاملSyntheses and reactivity of naphthalenyl-substituted arenediynes.
A series of naphthalenyl-substituted arenediynes were prepared to examine photochemical reactivity. For naphthalen-1-ylethynyl arenediyne, 350 nm photolysis resulted in a tandem [2 + 2] photocycloaddition to afford cyclobutene adducts. For naphthalen-2-ylethynyl derivatives, electron-donating methoxy substituents were found to facilitate C(1)-C(6) Bergman cyclization at 300 nm. Theoretical calc...
متن کاملSyntheses and properties of thienyl-substituted dithienophenazines
A series of dithienophenazines with different lengths of the oligomeric thiophene units (quaterthiophenes and sexithiophenes) was synthesized. The thiophene and phenazine units act as electron donors and acceptors, respectively, resulting in characteristic absorption spectra. The optical spectra were calculated using time-dependent density functional theory at the B3LYP/TZVP level and verify th...
متن کاملEnantioselective conjugate addition of 3-fluoro-oxindoles to vinyl sulfone: an organocatalytic access to chiral 3-fluoro-3-substituted oxindoles.
An organocatalytic conjugate addition of prochiral 3-fluorinated oxindoles to vinyl sulfones was described for the first time. In the presence of bifunctional tertiary amine-thiourea catalysts, 3-fluoro-3-substituted oxindole adducts were obtained in excellent yields and with high enantiomeric excesses.
