Copper-catalyzed asymmetric N-H insertion reactions: Couplings of diazo compounds with carbamates to generate α-amino acids

Lee, Elaine C.,Fu, Gregory C.

, p. 12066 - 12067 (2007)

A Cu/chiral bipyridine catalyst has been developed for the asymmetric insertion of α-diazocarbonyl compounds into the N-H bonds of carbamates to generate an array of easily deprotected arylglycines in good ee. With respect to the reaction partners, as wel
