Efficient routes to α-tert-butyl- and α-iso-propyl-ortho-hydroxybenzylamines 1a and 1b are described. Highly enantioenriched 1a and 1b were obtained by resolution of the methoxy derivatives 2 by recrystallization of the salts formed with mandelic a

Ein geeigneter CO--Ersatz sind elektronenarme, chirale Phosphanliganden, um zu effizienten Übergangsmetallkatalysatoren für die asymmetrische Diels-Alder-Reaktion zu gelangen. Dies belegt beispielsweise die Bildung von 1 mit > 99% ee aus Bromacrole
