Stereospecific Amination of Mesylated Cyclobutanol in Continuous Flow

We report an amination of mesylated cyclobutanol enabled by a multistep continuous flow process. The flow sequence involved an azidation followed by a Staudinger reduction which avoids the handling and isolation of a hazardous alkyl azide compound. The process is stereospecific with the azidation step proceeding to complete stereochemical inversion.
