چکیده
A condensação do 3-formilcromano (1) com tiazolidina-2,4-diona (2) produziu 5-[4-oxo-4Hcroman-3-ila)metileno]-1,3-tiazolidina-2,4-diona (3). A reação de 3 com hidrato de hidrazina, fenil hidrazina e hidrocloreto de hidroxilamina produziu os derivados correspondentes pirazol e isoxazol 4-7. O composto 3 reagiu com tiouréia, guanidina e cianoguanidina para produzir os derivados correspondentes de pirimidina 8-10. Pirimido[1,2-a]pirimidina 12, benzo[1,5]diazepina 15, pirido[1,2-b][1,2,3]triazepina 16, 1,2,4-triazolo[3,4-b][1,3,4]tiadiazepina 19 e 1,2,4-triazino[3,2-b] [1,3,4]tiadiazepina 20 ligados à tiazolidina-2,4-diona foram preparados a partir da reação de 3 com nucleófilos bifuncionais N,Ne N,S-. A reatividade química de 3 frente aos nucleófilos carbonados produziu novos derivados heterocíclicos de tiazolidina-2,4-diona 22-25. Os compostos sintetizados foram testados in vitro para verificar sua atividade antimicrobiana contra Staphylococcus aureus, Proteus vulgaris e Candida albicans.

Design, Synthesis and Characterization of Some Novel 3-Coumarinyl- 5-aryliden-1,3-thiazolidine-2,4-diones and Their Antioxidant Activity
In our effort to obtain biologically active compounds, new 3,5-disubstituted 1,3-thiazolidine-2,4diones (5a – r) were synthesized. A series of 5-arylmethylidene-1,3-thiazolidine-2,4-diones (3a – r) were prepared by Knoevenagel reaction from 1,3-thiazolidine-2,4-dione (2) and appropriate aromatic aldehydes. Condensation of 3a – r with 7-hydroxy-4-bromomethyl-2-oxo-2H-chromene (1) afforded novel ...

The synthesis and evaluation of the anticancer activity of 3'-aryl-5'-arylidene-spiro[3H-indole-3,2'-thiazolidine]-2,4'(1H)-diones and spiro[3H-indole-3,2'-thi-azolidine]-2,4'(1H)-dione-3'-alkanoic acid esters were described. The structure of the compounds was determined by (1)H and (13)C NMR and their in vitro anticancer activity was tested in the National Cancer Institute. Among the tested co...
متن کاملSynthesis and anticonvulsant activity of new 3'-aryl- 7-bromo-spiro[ [1]benzothiophene-3,2'-[1,3] thiazolidine]-2,4'-dione derivatives
Two series of spiro[ [1]benzothiophene-3,2'-[1,3]thiazolidine]-2,4'-diones 5a-e and 6a-e were synthesized, characterized and evaluated for anticonvulsant activity. Reaction of [1]benzothiophene-2,3-dione (3) with certain arylamines afforded the corresponding Schiff bases 4a-e. Cyclization of 4a-e with thioglycolic or thiolactic acids brought about the target spiro compounds 5a-e and 6a-e respec...

متن کاملSynthesis of Furo[2,3-d]pyrimidine-2,4(1H,3H)-diones From Alcohols Using T3P/DMSO
T3P/DMSO is shown to be an effective and mild reagent for the one-pot synthesis of furo[2,3-d]pyrimidine-2,4(1H,3H)-diones from a variety of alcohols. Alcohols are oxidized in situ to aldehydes under mild conditions, which undergo a three-component reaction with N,N'-dimethylbarbituric acid and various isocyanides to afford furo[2,3-d]pyrimidine-2,4(1H,3H)-diones in good yields.
