Facile reduction of coordinated α-imino acids to amino acids by dithionite and borohydride

Autor: Dierdre A. Pearce, Richard M. Hartshorn, Alan M. Sargeson

Publikováno v: Journal of the Chemical Society, Dalton Transactions. :1747-1752

Sodium dithionite was found to reduce a range of α-iminoacidato ligands, chelated to cobalt(III), to the related α-aminoacidato species. For the bis(1,2-ethanediamine) system, the distribution of the products showed a small stereoselectivity toward
