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 ...

A convenient and efficient synthesis of (S)-lysine and (S)-arginine homologues via olefin cross-metathesis

open access: yes, 2005
A convenient five step synthesis of (S)-homolysine, incorporating a key olefin cross-metathesis step in the chain extension methodology, has been developed, together with a six step related synthesis of a new homologue of arginine, (S ...

Turning the Light On: Recent Developments in Photoinduced Olefin Metathesis

open access: yes, 2017
Olefin metathesis is one of the most important methods to form carbon–carbon double bonds and has found many applications in industry and academia. The ability to initiate the reaction using external stimulus such as light, with high spatial and temporal

Ruthenium-Catalyzed Tandem Olefin Metathesis−Oxidations

open access: yes, 2016
The utility of Grubbs' 2nd generation metathesis catalyst has been expanded by the development of two tandem olefin metathesis/oxidation protocols. These ruthenium-catalyzed processes provide cis-diols or α-hydroxy ketones from simple olefinic starting ...
