摘要

AuCl-catalyzed intramolecular hydroamination of N-aryl-Opropargyl carbamates (3) efficiently affords (Z)-N-aryl-4-benzyliden-2-oxazolidinones (4) via a 5-exo dig cyclization.The reaction proceeds in acetonitrile at 60 °C and requires rBuOK or KOH as a base co-catalyst.It tolerates the presence of multiple substituted aryl units with electron donating methoxy groups.The method opens a convenient,flexible and operationally simple access to a new class of twisted molecules with potentially interesting biological properties.
