An oxime derivative of the formula:
wherein R is a hydrogen atom or a C1 -5 alkyl group, R1 is a hydrogen atom, a C1 -5 alkyl group or a carboxyl - protecting group, R2 is a hydrogen atom, a halogen atom, a hydroxyl group or an amino group, R3 is a C3-7 cycloalkyl group, R4 is a hydrogen atom, a halogen atom or a C1 -4 alkoxy group, each of R5 and R6 which may be the same or different, is a hydrogen atom or a C1-5 alkyl group, or R5 and R6 together represent a C2-4 alkylene group which forms together with the adjacent carbon atom a C3-5 ring, provided that when R2 is a hydrogen atom, R4 is a C1-4 alkoxy group, m is an integer of 0 or 1, and n is an integer of from 1 to 3; or its salt.
式中的肟衍生物:
其中 R 是氢原子或 C1 -5 烷基,R1 是氢原子、C1 -5 烷基或羧基保护基,R2 是氢原子、卤素原子、羟基或氨基,R3 是 C3-7 环烷基,R4 是氢原子、卤素原子或 C1 -4 烷氧基、R5和R6可以相同或不同,各自为氢原子或C1-5烷基,或R5和R6共同代表一个C2-4亚烷基,该亚烷基与相邻碳原子一起形成一个C3-5环,条件是当R2为氢原子时,R4为C1-4烷氧基,m为0或1的整数,n为1至3的整数;或其盐。
