Chiral 1,3-diarylimidazole salt carbene precursors, manufacturing methods, metal salt complexes and uses

摘要

The present invention discloses a novel chiral 1,3-diarylimidazole salt carbene precursor, a method for producing the same, a metal complex, and uses. The novel chiral 1,3-diarylimidazolium carbene precursor according to the present invention catalyzes an inactivated terminal olefin to react with a diboron reagent by forming a complex with copper. The problem is that high regioselectivity and high enantioselectivity give chiral martensitic borides, making it difficult for unactivated terminal olefins to directly form chiral martensitic borides via a hydroboration reaction. To solve. This is very important for expanding the variety of chiral alkyl boroides. And the new chiral N-heterocyclic carbene precursor has potential applications for asymmetric reactions catalyzed by various metals.
