| dc.description.abstract | Reactions of thiobenzamide or thioacetamide with 4-bromo-1,1-dimethyl-1,4-dihydroisoquinoline-3(2H)-one, 4-bromoisoquino-line-1,3(2H,4H)-dione and two alpha-bromo(phenyl)acetamides were examined under various conditions (base, solvent, thiophile, tem-perature) and structure/medium features that influence product distribution (Eschenmoser coupling reaction, Hantzsch thiazole syn-thesis and elimination to nitriles) were identified. The key factor that enables the successful Eschenmoser coupling reaction involves the optimum balance in acidity of nitrogen and carbon atoms of the intermediary alpha-thioiminium salts. | eng |
| dc.description.abstract-translated | Byly zkoumány reakce thiobenzamidu nebo thioacetamidu s 4-brom-1,1-dimethyl-1,4-dihydroisochinolin-3(2H)-onem, 4-bromisochinolin-1,3(2H,4H)-dionem a dvěma alfa-brom(fenyl)acetamidy za různých podmínek (báze, rozpouštědlo, thiofil, teplota). Dále byly identifikovány faktory jako např. vlastnosti struktury/média, které ovlivňují distribuci produktu (Eschenmoserova kopulační reakce, Hantzschova syntéza thiazolu a eliminace na nitrily). Klíčovým faktorem pro úspěšnou Eschenmoserovu reakci je acidita intermediární α-thioiminiové soli na atomech dusíku a α-uhlíku. | cze |
