The regioselective addition of aryl and aryldiazenyl substituents to olefinic substrates can be described as carbodiazenylation. In this report we present our final results relating to this unique type of radical functionalization reaction, which has now been developed into a convenient, versatile and highly effective synthetic method. Starting from an investigation into rate constants for the addition

Taking advantage of radical carboaminations producing azo compounds, a new chemo-enzymatic approach to enantiomerically enriched azo alcohols, beta-amino alcohols and non-natural (aromatic) amino acids with a quaternary stereocenter is reported. (C) 2010 Elsevier Ltd. All rights reserved.

The kineticenzymaticresolution of azo acetates via aminolysis with Candida antarctica lipase B has been investigated using benzylamine as amine component. The products obtained from this biotransformation in high enantiomeric purity can serve as valuable precursors for various amino alcohols, as exemplified by the synthesis of the serotonin reuptake inhibitor (S)-(+)-cericlamine.
