Abstract
Synthesis of some interesting heterocyclic compounds containing pyrimidine moiety
This thesis includes synthesis of 7-amino-5-(benzo[d][1,3]dioxol-5-yl)-4-oxo-2-thioxo-1,3,4,5-tetrahydro-2H-pyrano[2,3-d]pyrimidine-6-carbonitrile (2) and 7-amino-5-(benzo[d][1,3]dioxol-5-yl)-6-imino-2-thioxo-1,2,3,5,6,7-hexahydro-4H-pyrano[2,3-d:6,5-d’]dipyrimidin-4-one (10). Also, it studies the behavior of these compounds towards different chemical reagents to produce some heterocyclic compounds having expected antimicrobial activities.
