transition‐metal catalysis. Unlike all known helical phosphines used so far in catalysis, the phosphorus function of phosphahelicenes is embedded in the helical structure itself. This crucial structural feature originates unprecedented catalytic behaviors and efficiency. An appropriate design and fine tuning allowed both high catalytic activity and good enantiomeric excesses to be attained in the gold promoted
本文公开了在过渡金属催化中磷腈作为手性配体的首次用途。与迄今为止在催化中使用的所有已知螺旋膦不同,磷杂环戊烯的磷官能团嵌入在螺旋结构本身中。这种关键的结构特征引发了前所未有的催化行为和效率。适当的设计和微调允许在N系链的1,6-炔和二烯的金促进的环异构化过程中实现高催化活性和良好的对映异构体过量。
