Hydroxynitrile lyase-catalyzed addition of HCN to 4-substituted cyclohexanones: Stereoselective preparation of tetronic acids

Effenberger, Franz,Roos, Juergen,Kobler, Christoph,Buehler, Holger

, p. 671 - 679 (2007/10/03)

The addition of HCN to 4-alkylcyclohexanones 1 to give cyanohydrins 2 is strongly catalyzed by hydroxynitrile lyases (HNLs). With PaHNL, from bitter almond, trans-addition occurs almost exclusively, yielding trans-2. With MeHNL, from cassava, cis-addition
