Jaunu alkilaizvietotu 4-fenil-2-pirolidonu sintēze un ķīmisko īpašību izpēte
2016
Jaunu alkilaizvietotu 4-fenil-2-pirolidonu sintēze un ķīmisko īpašību izpēte. Baškevičs V., darba vadītāji: Dr.chem. Maksims Vorona, asoc. prof. Anda Prikšāne. Bakalaura darbs. 32 lappuses, 18 attēli, 18 literatūras avoti. Latviešu valodā. Izstrādātas jaunas 5-alkilaizvietoto 4-fenil-2-pirolidonus iegūšanas metodes, izmantojot malonātu vai 2-fluormalonāta esteru Mihaela pievienošanu -alkil--nitrostirolam, kā arī nitroalkānu pievienošanu kanēļskābes metilesterim. Iegūtie starpprodukti tika hidrogenēti paaugstinātā spiedienā Reneja niķeļa katalizatora klātbūtnē, veidojot 5-alkil-4-fenil-3-karboksi-2-pirolidonu un 5-metil-4-fenil-3-fluoro-3-karboksi-2-pirolidona esterus, vai 5-alkil-4-fenil-…

Unexpected Behavior of Enaminones: Interesting New Routes to 1,6-Naphthyridines, 2-Oxopyrrolidines and Pyrano[4,3,2-de][1,6]naphthyridines
2012
Reaction of enaminones 1a–d with 2-aminoprop-1-ene-1,1,3-tricarbonitrile (2) in the presence of AcOH/NH4OAc afforded 7-amino-5-oxo-5,6-dihydro-1,6-naphthyridine-8-carbonitrile derivatives 9a–d. On the other hand, 2-aminopyrano[4,3,2-de] [1,6]naphthyridine-3-carbonitriles 20a–c,e were the only obtained products from the reactions of 1a–d with 2 in the presence of AcOH/NaOAc, while 1d afforded [3,5-bis-(4-chloro-benzoyl)-phenyl]-(4-chloro-phenyl)-methanone 21 under the same condition. The reaction of 2 with diethyl acetylenedicarboxylate in the presence of AcOH/NH4OAc afforded (4-cyano-5-dicyanomethylene-2-oxo-2,5-dihydro-1H-pyrrol-3-yl)-acetic acid eth…
New Tripentone Analogs with Antiproliferative Activity
2017
Tripentones represent an interesting class of compounds due to their significant cytotoxicity against different human tumor cells in the submicro-nanomolar range. New tripentone analogs, in which a pyridine moiety replaces the thiophene ring originating the fused azaindole system endowed with anticancer activity viz 8H-thieno[2,3-b]pyrrolizinones, were efficiently synthesized in four steps with fair overall yields (34–57%). All tripentone derivatives were tested in the range of 0.1–100 μM for cytotoxicity against two human tumor cell lines, HCT-116 (human colorectal carcinoma) and MCF-7 (human breast cancer). The most active derivative, with GI50 values of 4.25 µM and 20.73 µM for HCT-116 a…
