Stereocontrol in Conformationally Stable C(sp2)─C(sp3) Atropisomers

Angewandte Chemie, Volume 137, Issue 28, July 7, 2025.
Building in our expertize in the synthesis of trans‐dihydrobenzofurans via organocatalyzed domino Michael/O‐cyclization between β‐naphthols and nitroalkenes, we developed an efficient strategy to access a new family of atropisomers bearing a conformationally stable C(sp2)─C(sp3) bond and two stereogenic centers through simple and highly ...
