Organocatalyzed Michael addition of N-substituted tetramic acids to nitroalkene acceptors followed by O-alkylation gave polyfunctionalized tetramic acid (31 examples, 59–94% ee). The enantioselectivity of the product was influenced by the N-substit

Metodologije priprave kiralnih β,β-diaril ketona temelje se uglavnom na arilacijama 1,4- nezasićenih ketona u prisutnosti kiralnih kompleksa prijelaznih metala kao katalizatora. Iako u većini slučajeva generiraju tercijarni centar kiralnosti na

Iz (1S)-(+)-10-kafrasulfonske kisline sem prek štirih reakcij uspešno pripravil želeni N-benzilamid ketopinske kisline. Za sintezo ketopinske kisline sem poskusil dva sintezna postopka. Prvi je dal s PCl5 slab izkoristek in nizko čistost nastale

V uvodnem delu diplomskega dela so predstavljene Diels–Alderjeve reakcije, njihova stereokemija in regioselektivnost. Opisane so tudi značilnosti sodelujočih dienov in dienofilov. Večji poudarek je namenjen 2H-piran-2-onom, ki predstavljajo zani

Arylidene-Δ2-pyrrolin-4-ones undergo organocatalyzed annulation with malononitrile, furnishing dihydropyrano[3,2-b]pyrroles (18 examples, 0–77% ee in dichloromethane, 11–44% ee in methanol). The products could be enantiomerically enriched by tri

V sklopu magistrskega dela sem se ukvarjal z organokatalizirano asimetrično [4+2] anuluacijo (hetero)arilidenskih derivatov Δ2-pirolin-4-ona z malononitrilom. Na modelni asimetrični pretvorbi N-metil substituiranega benzilidenskega Δ2-pirolin-4-o

Pirazoloni in njihovi derivati so zaradi številnih bioloških aktivnosti in strukturnih lastnosti zelo pomembne potencialne učinkovine v medicini, agrokemiji in farmaciji. Kiralni derivati morajo imeti točno določeno stereokemijo, zato pri sintez
