Abstract
Pyrrolidines and piperidines are important heterocyclic cores of several natural products [1] and, as such, have always attracted the attention of chemists. As a result of this interest, several synthetic methodologies have been developed, [2] with one of the most common being the cyclization of alkenes bearing an internal nucleophile, using electrophiles such as H + , Pd 2+ , PhS + or PhSe + . Iodocyclization of homoallylic tosylamides has been shown to be a smooth ...
