Enantioselective Mukaiyama Aldol Reactions with Glyoxylates

Significance The enantioselective aldol reaction is among the most useful and well-developed transformations for the synthesis of chiral materials. Despite this, gaps in asymmetric aldol methodology still exist. The authors present the first ­example of a general, highly enantioselective ­Mukaiyama aldol reaction between aryl ketones and glyoxylates. An indium-PyBox complex is used as a chiral Lewis acid to induce asymmetry.
