α-Aminoalkylcopper reagents prepared from soluble CuX·2LiCI give modest to good yields of α-aminoketones upon reaction with acid chlorides, Higher yields are generally obtained with CuCl·2LiCl than with CuCN·2LiCl. Improved yields can be obtained by utilization of cuprate reagents prepared from CuCN·2LiCl and 2.0 equivalents of α-lithiocarbamates.
