The stereoselective synthesis of heterocycles through cation-triggered annulation

The stereoselective synthesis of heterocycles through cation-triggered annulation

<p>The work described herein details the development of new methodologies for the synthesis of 2,3-disubstituted pyrrolidines and piperidines <em>via</em> an <em>endo-trig</em> cyclisation. This was realised through two approaches: firstly, a Lewis acid catalysed cation...
