The asymmetric copper-catalyzed addition of dialkylzinc to enals followed by organocatalyzed one-pot aldehyde α-functionalization has been accomplished providing CC, CCl or CF bond formation. These simple procedures led to the creation of two contiguous stereocenters in excellent enantioselectivities (typical ee=99%). This methodology has been applied in the synthesis of (2S,3S) isomer of Valnoctamide®.
