Sažetak
Bifunkcionalni derivati pirazolopiridina (2) i piranopirazola (3) pripravljeni su reakcijom 2-(2,4-dinitrofenil)-5-metil-2,4-dihidro-3H-pirazol-3-ona (1) s p-metoksibenzaldehidom, malononitrilom u prisutnosti amonijevog acetata ili piperidina. Iz spoja 2 su pripravljeni derivati pirazolopiridopirimidina reakcijom s mravljom kiselinom, smjesom formamida-mravlje kiseline-DMF, amonijevim tiocijanatom ili s trietil ortoformatom, te naknadnom ciklizacijom s hidrazin hidratom. Reakcija spoja 3 s trietil ortoformatom te cillizacijom s hidrazin hidratom dobiveni su derivati pirazolo-pirano-pirimidina (11). Reakcijom etil-3-okso-2-[2-fenil-diazenil]butanoata i etil 2-[2-(4-klorfenil)diazenil]-3-oksobutanoata sa spojem 1 sintetizirani su derivati pirazolona 13a i 13b.

Ključne riječi
derivati pirazolopiridina; derivati piranopirazola; sinteza
