摘要

Catalytic enantioselective construction of chiral quaternary stereocenters is a formidable challenge. 1 For this type of reaction to proceed successfully, catalysts must differentiate between the subtle sterical differences of substituents on a pro-chiral carbon that lacks the remarkably small hydrogen. In addition, catalysts must activate substrates more strongly than in cases of chiral tertiary stereocenter construction, due to higher steric repulsion ...
