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.
通过在Δ4,5-噁唑烷-2-酮的 4 位进行分子内自由基环化,得到 C2 对称的 2,5-二苄氧基吡咯烷-2-酮,从而实现了反式 5-取代的 2-羟甲基吡咯烷衍生物的新的高对映选择性合成。
