摘要
The first enantioselective synthesis of axially chiral styrene-type allylamines was achieved through chiral phosphoric acid mediated atroposelective reductive amination of 1-enal substituted 2-naphthols.This protocol features a broad substrate scope,good enantioselectivities(up to 90%ee)and mild reaction conditions,thus providing a new entry to the challenging atropisomeric acyclic styrene scaffolds.
