## Abstract

β-Amino acids
serve as essential motifs in a wide array of
bioactive compounds, pharmaceuticals, and natural products, playing
a crucial role in the development of peptides and peptidomimetics.
Transition-metal-catalyzed carbonylative functionalization represents
an ideal strategy for synthesizing carbonyl-containing compounds.
In this context, we disclose a primary tosyl amidyl radical initiated
1,2-amino-alkoxycarbonylation of unactivated alkenes, which offers
a straightforward and efficient approach to synthesize β-amino
acid derivatives.
