Published: Nov. 7, 2024

Abstract Precise synthesis of carboxylic acids via catalytic carboxylation with CO 2 is highly appealing. Although considerable advancements have been achieved in difunctionalizing unsaturated hydrocarbons, the asymmetric variants are conspicuously underdeveloped, particularly addressing axially chiral alkenes. Herein, we report first atroposelective alkynes . A variety valuable obtained good yields and high chemo‐, regio‐, Z/E enantio‐selectivities. Notably, an unexpected anti ‐selective carbo‐carboxylation observed sp ‐hybrid carbo‐electrophile‐initiated reductive alkynes. Mechanistic studies including DFT calculation elucidate origin induction ‐selectivity vinyl‐carboxylation
