Synthesis of some coumarin derivatives of possible biological activity

ABSTRACT

A series of bromocoumarins incorporated with aromatic derivatives via amino and ether linkages were synthesized. Also, hydrazocoumarin incorporated with thiosemicarbazides were prepared. Azole ring systems as 1,3,4-thiadiazole and 1,2,4-triazole were synthesized. Schiff bases which were cyclized with thioglycolic acid were prepared. Isatin moiety attached to hydrazocoumarin was prepared. The biological activity of some newly prepared compounds were carried out
