Isomerization of α‐Pinene Oxide to Trans‐Pinocarveol

Helvetica Chimica Acta, Volume 109, Issue 1, January 2026.
An operationally simple protocol for the selective isomerization of α‐pinene oxide (APO) to trans‐pinocarveol (TPC) is disclosed, which leverages inexpensive pyridinium‐halide organocatalysts to mitigate competing 1,2‐alkyl shifts. The scalability of this methodology is demonstrated on a decagram scale and catalyst‐recycling is validated through the ...
