Alternative Groups
You can create a search query that contains variable functional groups or substructures. Instead of submitting multiple queries on structures that share a common substructure, you can submit a single query with the parent structure. The parent structure can have attachment points to a list of alternative groups that you can define.
Alternative groups, sometimes called R-Groups, G-Groups, or Generic Groups, are shown below.
