摘要：

Synthesis of novel isoxazolo[2 '',3 '': 1',2']pyrimido[4',5':4,5]pyrimido[6,1-b]quinazoline-8-ones 6a-j, has been achieved by reaction of 5-amino-2-methyl-7-phenyl-7H-isoxazolo[2,3-a] pyrimidin-6-yl cyanides 4, with dimethyl formamide dimethylacetal followed by treatment with anthranilic acids in situ in one-pot. The key intermediate, viz., 5-amino-2-methyl-7-phenyl-7H-isoxazolo[2,3-a]pyrimidin-6-yl cyanide 4 is obtained by reaction of 3-amino-5-methyl isoxazole with aromatic aldehydes and malononitrile by a three-component one-pot process. The newly synthesized compounds 6a-j have been evaluated for their in vitro anticancer and antimicrobial activity. Compounds 6e and 6f exhibit potent anticancer and antimicrobial activity comparable to that of standard drugs.
