Synthesis of Chiral 1-Arylalkan-1-ols Using Crude Enzymes
摘要:
Enantioselective hydrolysis of racemic l-acetoxy-l-arylalkanes has been examined by two selected enzymes, crude pig liver acetone powder and crude goat liver acetone powder, providing l-arylalkan-l-ols in high optical purities.

with regioselectivity. An alternative approach is to use ubiquitous carboxylic acids as starting materials and perform a decarboxylative coupling. Herein, we report conditions for a photocatalytic decarboxylative C-O bond formation reaction that provides rapid and facile access to the corresponding acetoxylated products. Mechanistic investigations suggest that the reaction operates via oxidation of the
