研究了手性PYBOX-DIPH-Zn(II)配合物催化吡咯与2-烯酰基吡啶N-氧化物的傅-克烷基化反应。该催化剂具有很大的底物范围,并以优异的产率(高达99%)和对映选择性(高达> 99%ee)提供烷基化吡咯。
A highly enantioselective Friedel-Crafts alkylation of pyrroles with 2-enoylpyridine N-oxides catalyzed by chiral PYBOX-DIPH-Zn(II) complexes has been developed. The catalyst otters substantial substrate scope and furnished alkylated pyrroles in excellent yields (up to 99%) and enantioselectivities (up to >99% ee).
