4-tert-butyl-phenyl substituted (R)-[H8]-BINOL chiral calcium phosphate catalyzedenantioselectiveamination of 3-aryl-2-benzofuranones with dibenzyl azodicarboxylate is described. The catalyst loading of the reaction is 1 mol %. This transformation is facile and has a high degree atom economy, which gave products with good yields and high enantioselectivities (79% to 99%). This reaction has excellent ee
