The Preparation and Intramolecular Radical Cyclisation Reactio
O éter-oxima quiral 2 e o éster-oxima 4 foram preparados para alquilação e esterificação da oxina 1. Hidroxiamina racêmica 6 e a hidroxiamina 10 foram sintetisadas a partir de N-hidroxipucanimida e o álcool correspondente na presença de di etil azodicarboxilato, e os dois produtos convertidos nos éteres-oximas 7 e 11 respectivamente. As reações de ciclização radicalar intramoleculares desses ét...
متن کاملSynthesis of heteroarenes using cascade radical cyclisation via iminyl radicals.
Cascade radical cyclisation involving homolytic aromatic substitution has been used to synthesise new tetracycles. Treatment of vinyl iodide radical precursors with Me(3)Sn. radicals (from hexamethylditin) yielded intermediate vinyl radicals which undergo 5-exo cyclisation onto suitably placed nitrile groups to yield intermediate iminyl radicals. The iminyl radicals undergo aromatic homolytic s...
متن کاملFormation of N-bridgehead 1,2,5-thiadiazolium and selenadiazolium rings through an intramolecular cyclisation reaction.
Treatment of N-lithiopyridylketimide derivatives Li[R(C=N)py] (R=Ph, py) with ECl(2) (E=S, Se) affords the fused thiadiazolium and selenadiazolium salts [RC(6)H(4)N(2)E]Cl [1]Cl and [2]Cl containing a bridgehead N atom through intramolecular coordination.
متن کاملA facile synthesis of pyrrolo-(di)-benzazocinones via an intramolecular N-acyliminium ion cyclisation.
A facile, moderate to high yielding synthesis of hexahydro-(di)-benzazocinones is described via an intramolecular N-acyliminium ion cyclisation. The iminium ion intermediates are formed from the readily available 4,4-diethoxybutyl amides with an excess of triflic acid. For electron-withdrawing substituents, better yields were obtained from the pre-formed 2-hydroxypyrrolidine amides. From NMR st...
