We report an optimised synthetic approach to the chiral derivatising agent (5R)-methyl-1-(chloromethyl)-2-pyrrolidinone. In addition, the observation of an unwanted dimerisation product is turned to our advantage by providing a method for the synthesis of a new class of C2-symmetric chiral diphosphine.

Starting from the readily available 5-oxo-2-carboxypyrrolidine, methylene-bis-(N-5-oxo-2-carboxypyrrolidine) was prepared and transformed into a diamine, then into two isomeric diols, which cyclised into one ether.The meso configuration has been assigned for this ether.The reduction of both diols and ether was complete and gave rise to methylene-bis-N-pyrrolidine.
