title: Preparation of a library of unsymmetrical ureas based on 8-azabicyclo[3.2.1]octane scaffold.
abstract: This paper reports the preparation of a library of unsymmetrical ureas based on 8-azabicyclo[3.2.1]octane scaffold. The reported synthetic route uses nortropane-8-carbonyl chlorides as key intermediates that, when treated with a slight excess of amine, give the corresponding ureas in high yield (129 examples).
