A convergent route to functional protected amines, diamines, and β-amino acids
摘要:
Phthalimide protected amines react with NBS under peroxide initiation to give geminal phthalimidobromo derivatives, which are readily converted into the corresponding xanthates. These xanthates in turn undergo radical additions to numerous olefins, providing a convergent and modular access to densely functionalized protected amines and diamines. (C) 2014 Elsevier Ltd.

palladium-catalyzed intermolecular aminocarbonylation of alkenes has been developed in which the employment of hypervalent iodine reagent can accelerate the intermolecular aminopalladation, which thus provides the successful catalytic transformation. The current transformation presents one of the most convenient methods to generate β-amino acid derivatives from simple alkenes.
