The object of the present invention are novel compounds of azetidine-2-one substituted in 1-position with different isothiazolidinone radicals, as analogons of a beta-lactam structure, of the general formula I
wherein
R1 represents a hydrogen or a halo atom,
R2 represents a hydrogen or a halo atom or a phthalimide group,
R3 represents a hydrogen or a halo atom,
R4 represents a hydrogen or a halo atom,
R5 represents a hydrogen atom, a lower linear or branched alkyl, aryl or aralkyl, or a radical containing a heterocycle with one or more heteroatoms, such as isoxazolyl or pyrazolyl, and
n is 0, 1 or 2.
The usefulness of these compounds as intermediates for the preparation of novel beta-lactam analogons or active substances in formulations for antimicrobial therapy is given.
本发明的对象是一种新型的2-氧代氮杂环戊烷化合物,其在1-位上以不同的异噻唑啉酮基团进行取代,作为β-内酰胺结构的类似物,其一般式为I式,其中R1表示氢或卤素原子,R2表示氢或卤素原子或邻苯二甲酰亚胺基团,R3表示氢或卤素原子,R4表示氢或卤素原子,R5表示氢原子、较低的线性或支链烷基、芳基或芳基烷基,或含有一个或多个杂环原子的基团,例如异噁唑基或吡唑基,n为0、1或2。这些化合物作为新型β-内酰胺类似物的中间体或用于抗微生物治疗配方中的活性物质的有用性得到了证明。
