The enantiospecific synthesis of a series of 2(S)-alkylpyrrolidines from 2-cyano oxazolopyrrolidine synthon is described. Two of the synthesised compounds represent key intermediates towards ozabicyclic alkaloids.
[GRAPHICS]A new diastereoselective synthesis of pyrrolidines from readily available chiral N-allyl oxazolidines is presented. The construction of the pyrrolidine ring is achieved via a tandem hydrozirconation-stereoselective Lewis acid mediated cyclization sequence.
