The scope of the phthalimido protecting group (PhthN-) is extended with pyrrolidine. The resulting omicron-pyrrolidinocarbonylbenzamide (''OPCB-'') represents a base/nucleophile stable derivative of the parent, which reverts to the imide form upon treatment with acid. This methodology allows utilization of this protecting group (as the OPCB form) in synthetic sequences requiring basic/nucleophilic reaction conditions.
