NEW MATERIAL:A compound expressed by formula I [R1 and R2 are H or lower alkyl; X is F, -OR3, -SR3, -NR3R4 [R3 and R4 are H, lower alkyl or ben zyl); Y is halogen or (substituted)cyclic amino (the cyclic amino may contain other hetero atom); Z is O or S; provided that when X is amino, Y is formula II (R5 and R6 are H or lower alkyl)], ester thereof and salt thereof. EXAMPLE:9-Fluoro-8-hydroxy-3-methyl-10-(4-methyl-1-piperazinyl)-7-oxo-2, 3-dihy dro-7H-pyrido[1,2,3-de][1,4]benzoxazine-6-carboxylic acid. USE:A germicide, agricultural chemical and preserving agent for food. PREPARATION:A compound expressed by formula III (X1 and X2 are halogen; R7 is H or lower alkyl) or compound expressed by formula IV is subjected to ring closure in the presence of a fluorine salt or strong base.
