Chiral lithium amide mediated asymmetric synthesis of 3-aryl-3,4- dihydroisocoumarins
An asymmetric synthesis of 3-aryl-3,4-dihydroisocoumarins using the reaction of laterally lithiated 4,4-dimethyl-2-(o-tolyl)oxazoline with aromatic aldehydes, in the presence of an external chiral ligand, gave products with enantiomeric excess (ee) in the range of 60-70%. ARKAT USA, Inc.
