Patent number: 6716987
Abstract: An oxygen-containing heterocyclic compound represented by following Formula (I):
wherein R1 and R2 independently represent hydrogen, lower alkyl, cyano, —(CH2)n—E1—CO—G1 (wherein E1 represents a bond, O, or NH; and G1 represents hydrogen, substituted or unsubstituted lower alkyl, OR6, or NR7R8; and n represents an integer of 0 to 4), or the like; R1 and R2 are combined to represent a saturated carbon ring together with a carbon atom adjacent thereto; or R2, and R11 or R13 described below are combined to form a single bond; R3 represents hydrogen, phenyl, or halogen; R4 represents hydroxy, lower alkoxy, or the like; A represents —C(R9)(R10)— or O; B represents O, NR11, —C(R12)(R13)—, or —C(R14)(R15)— C(R16)(R17)—; D represents (i) —C(R18)(R19)—X— (wherein X represents —C(R21)(R22)—, S, or NR23), (ii) —C(R19a)═Y— [Y represents —C(R24)—Z— (wherein Z represents
