A recent study conducted at Shanghai Normal University in China focused on the direct asymmetric alpha-C-H functionalization of N-unprotected allylamine using chiral pyridoxal as a catalyst. The research aimed to produce alpha-trifluoromethyl-beta-amino alcohols with high yields and enantiomeric excess. While the diastereoselectivity of the products was not optimal, the study demonstrated the potential of chiral pyridoxal for asymmetric alpha-C-H functionalization of primary amines. This peer-reviewed research provides valuable insights into the field of organic synthesis and catalysis. [Extracted from the article]
