利用环信息检索配位化合物

Searching for Complex Using Ring Index Code

检索案例涉及一系列有机化合物,对于这类案件,本领域首选采用STN数据库进行检索,除采用CAS号进行新颖性文献检索外,还需采用结构检索的方式检索创造性文献。在结构检索中除了画结构检索外,Registry数据库还有很多特殊字段,例如,针对本案所用的环系信息代码,由于申请涉及的具体化合物都具有明确且唯一的母环结构,审查员在掌握环系标引规则的前提下,不需要绘制结构检索,就可以快速获得对比文件。

This search case involves a series of specific organic compounds.For such cases,STN database is pre?ferred for retrieval in this field.In addition to retrieving novelty literature by CAS number,structural retrieval is also required for retrieving creative literature.Besides drawing structure in the structure retrieval,there are many special fields in Registry Database,such as Ring Index Code used in this case,the specific compounds are having the clarity and unique female-ring structure,under the premise of mastering of Ring Index rules,the examiner can quickly re?trieve to get comparative documents without drawing structure.
