Abstract

A three step synthesis of (S)-2(diphenylmethyl)pyrrolidine 4 is described which allows its preparation on a large scale. The C-2 symmetric diamines 5 and 6 have been prepared from 4 and are attractive as potential ligands for asymmetric transformations. Pyrrolidine 4 has been assessed as a chiral solvating agent for the NMR analysis of chiral compounds. It emerges as a good CSA for carboxylic acids and some secondary alcohols.
