As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. category: chiral-oxygen-ligands, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 4254-15-3
The first successful asymmetric reduction of unhindered aliphatic ketones with B-chlorodiisopinocampheylborane is reported. In contrast to the reduction in high ee of aralkyl ketones, such as acetophenone, with the reagent, the reduction of unhindered dialkyl ketones, such as 3-methyl-2-butanone, provides only poor ee. However, treatment of alpha- and beta-hydroxyketones with one equiv of diisopnocampheylborane or B-chlorodiisopinocampheylborane rapidly produces the corresponding ketoalkyl diisopinocampheylborinate intermediates, which then undergo facile intramolecular reduction. This reaction sequence, followed by oxidative workup, provides a general synthesis of 1,2- and 1,3-diols in 84?99% enantiomeric excess.
