Enantioselective four-component reactions of aryl diazoacetates with alcohols, aldehydes and amines catalyzed cooperatively by a rhodium complex and a chiral Bronsted acid produce beta-amino-alpha-hydroxyl acid derivatives in a single step with excellent control of chemo-, diastereo- and enantioselectivity.

An asymmetric three-componentreaction of diazocompounds and alcohols with imines catalyzed cooperatively by a rhodium complex and a chiral Brønsted acid provides a general and efficient entry to beta-amino-alpha-hydroxyl acid derivatives in high yields with excellent stereoselectivities.
