No presente trabalho de investigação foi sintetizada uma nova série de derivados de 1,3,4-oxadiazóis e pirazolonas. Os derivados de 2-mercapto-1,3,4-oxadiazol foram sintetizados através da reação da hidrazida ácida correspondente com dissulfureto de carbono, seguida da condensação do átomo de hidrogénio ativo do grupo 2-mercapto do 5-aril-2-mercapto-1,3,4-oxadiazol com 2-cloro piridina, 4-cloro anilina e epicloridrina para dar derivados de 5-aril-2-(ariltio substituído)-1,3,4-oxadiazol (A1-3, B1-4). Os derivados 5-(aril substituído)-1,3,4-oxadiazóis foram sintetizados por reação da hidrazida de ácido salicílico com ácido aromático para dar derivados 5-(2-hidroxi-fenil)-2-aril-1,3,4-oxadiazóis (A4-6): Os derivados de 3-metil-pirazol-5(4H)-ona foram sintetizados através da reação da hidrazida ácida correspondente com acetoacetato de etilo para dar 1-(arilo substituído)-3-metil-1H-pirazol-5(4H)-ona. Seguiu-se a condensação do átomo de hidrogénio ativo de -CH2- da pirazolona com hidrazina do ácido isonicotínico/ácido p-amino salicílico/sulfanilamida/5-amino tetrazol/ hidrazida do ácido pirazinóico/2-amino pirazina para obter os derivados de pirazolona correspondentes (A7-11, B5-9).
