  A Catalytic Asymmetric Reaction Involving Enolizable Anhydrides

  摘要：

  In the presence of a highly efficient novel bifunctional organocatalyst at low loadings under mild conditions, enolizable homophthalic anhydrides can be added to a range of aromatic and aliphatic aldehydes to give dihydroisocoumarins, with excellent yields and diastereo- and enantiocontrol (up to 99% ee).

  Disclosed herein is enantioselective synthetic method comprising reacting an enolisable C 4 -C 50 organic anhydride with a second compound selected from the group consisting of an aldehyde, a ketone, an aldimine, a ketimine or a Michael Acceptor in the presence of a bifunctional organocatalyst. The reaction may find particular utility in the enantioselective synthesis of medicinally relevant heterocycles, such as dihydroisocoumarins and dihydroisoquinolinones.
