    3-benzoyl-4-hydroxyisochromen-1-one derivatives, their synthesis and synthetic application

  • Original language description

    3-Benzoyl-1,4-isochromandione derivatives were prepared by cyclization of phenacyl phthalates (2). The cyclization was done in the presence of N-methylpyrrolidone and potassium hydroxide. These compounds served as intermediates for the synthesis of morecomplicated isocoumarine derivatives. A Wittig reaction with (carbethoxymethylene)triphenyl phosphorane was conducted in a microwave reactor and resulted in the formation of substituted 4-phenylpyrano[3,2-c]isochromene-2,6-dione.

  • Czech description

    Deriváty 3-benzoyl-4-hydroxyisochromen-1-onu byly připraveny cyklizací příslušných fenacylftalátů. Cyklizace byla prováděna v přítomnosti N-methylpyrrolidonu za katylýzy hydroxidem sodným. Uvedené sloučeniny sloužily jako meziprodukty pro yntézu složitějších isokumarinových derivátů. Wittigova reakce s (carbethoxymethylene)triphenyl phosphoranem byla provedena v mikrovlnném reaktoru za vzniku výsledného substituovaného 4-phenylpyrano[3,2-c]isochromene-2,6-dionu.
