Blackmond and co-workers could indeed show that the use of tetraalkylammonium prolinates also resulted in a similar reversal of the enantioselectivity as observed for the addition of strong bases. See ref. [10a]. Note added in proof: Enamine carboxylate intermediates were also detected in a very recent study by Armstrong, Blackmond, and Houk
