Synthesis of naphtho[2,1-b]furo[3,2-e]-1,4-diazepin-2-ones and naphtho[2,1-b]furo[3,2-e]-1,3,4-triazepin-2-ones of pharmacological interest

2-Hydroxy-1-naphthonitrile 1 on treatment with different haloketones affords corresponding 2-acyl-3-amino-naphtho[2,1-b]furans 2a-c. The compounds 2a-c on refluxing with chloroacetyl chloride produce 3-chloroacetamido-2- acylnaphtho[2,1-b]furans 3a-c, whi
