efficient Pd-catalyzed cyclizations of oxime esters with 1,1-disubstituted alkenes as the basis of a general entry to alpha,alpha-disubstituted pyrrolidine derivatives. We also demonstrate that catalytic asymmetric variants of this chemistry are feasible by employing a suitable chiral ligand.
我们报告有效的钯催化的肟酯与1,1-二取代的烯烃的Pd催化环化,作为一般进入α,α-二取代的吡咯烷衍生物的基础。我们还证明通过采用合适的手性配体,该化学方法的催化不对称变体是可行的。
