用于实现烷基亲电子试剂(SN 1和SN 2)的亲核取代的经典方法具有有限的范围,并且通常不适用于采用容易获得的外消旋亲电子试剂的对映选择性变体。手性过渡金属配合物催化的基于自由基的途径为解决这些限制提供了一种有吸引力的方法。由手性过渡金属络合物催化的基于自由基的途径解决了经典SN1和SN2反应的局限性。
Classical methods for achieving nucleophilic substitutions of alkyl electrophiles (SN1 and SN2) have limited scope and are not generally amenable to enantioselective variants that employ readily available racemic electrophiles. Radical-based pathways catalyzed by chiral transition-metal complexes provide an attractive approach to addressing these limitations. Radical-based pathways catalyzed by chiral transition-metal complexes address limitations of classical SN1 and SN2 reactions.
