Installing multiple functional groups on biodegradable polyesters via post-polymerization olefin cross-metathesis

open access: yes, 2016
Olefin cross-metathesis is an effective tool for the functionalization of biodegradable aliphatic polyesters through both pre- and post-polymerization of ß-heptenolactone (ßHL).

Chelation‐Assisted Metal‐Catalyzed Ligation and Cleavage Reactions for Chemical Biology

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 39, 22 October 2026.
Chelation‐assisted transition metal catalysis has emerged as a promising complement to bioorthogonal click chemistry for studying biological processes. By pre‐organizing catalytic metal centers, designed coordinating substrates enhance reactivity and biocompatibility, enabling site‐selective ligation and decaging reactions in complex biological media ...

Cross metathesis of allyl alcohols

open access: yes, 2013
Under standard conditions the cross metathesis of allyl alcohols and methyl acrylate is accompanied by the formation of ketones, resulting from uncontrolled and undesired double bond isomerization. By conducting the CM in the presence of phenol, the catalyst loading and the reaction time required for quantiative conversion can be reduced, and ...
