A new enantioselective synthesis of trans 2,5-disubstituted pyrrolidine derivatives by radical cyclisation
Abstract
A new and highly enantioselective synthesis of trans 5-substituted 2-hydroxymethylpyrrolidine derivatives is achieved by intramolecular radical cyclization at the 4-position of Δ4,5-oxazolidin-2-one, which leads to C2-symmetrical 2,5-dibenzyloxypyrrolidin-2-one.
