Abstract
A direct regioselective α-hydroxyamination of α-branched aldehydes with nitrosobenzene using cis-5-benzylproline as catalyst has been developed for the preparation of α-hydroxyamino aldehydes possessing a quaternary carbon center. Such compounds are versatile building blocks for the synthesis of quaternary α- amino acids, β-amino alcohols, and 1,2-diamines.
