Amide‐Enabled Reversal of Regioselectivity in Carbonyl‐Substituted Allenes

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 20, 16 October 2026.
A substrate‐embedded secondary amide reverses the inherent regioselectivity of carbonyl‐substituted allenes, enabling rhodium‐catalyzed α‐acyloxylation with carboxylic acids. This redox‐neutral method requires no external oxidants or auxiliary‐type directing groups and tolerates diverse carboxylic acids.

Synthesis and Polymerization of a Lactone Building Block Derived From Cashew Nut Shells

open access: yesChemSusChem, Volume 19, Issue 19, 14 October 2026.
Cardanol as a renewable substituted phenol feedstock was selectively transformed into the corresponding cyclohexanone derivative by means of a partial metal‐catalyzed hydrogenation. Subsequent conversion via Baeyer–Villiger oxidation gave a lactone product consisting of a mixture of regioisomers, which has been readily converted into its homopolymer ...
