Pyrrolidines are an important class of five-membered heterocycles with remarkable biological properties [1]. In addition to pharmaceutical applications, the pyrrolidine moiety has also seen wide use as a chiral auxiliary for asymmetric synthesis [2]. Accordingly, development of efficient general methods for the preparation of chiral, non racemic pyrrolidines is of significant value and an increasing number of papers and reports recently appeared in the literature [3]. ...
