Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis

European Journal of Organic Chemistry, Volume 29, Issue 32, 24 August 2026.
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

HCo(PMe3)4‐Catalyzed 1,2‐Selective Hydroboration of Quinolines: Access to Isolable N–B and N–H 1,2‐Dihydroquinolines

European Journal of Organic Chemistry, Volume 29, Issue 31, 19 August 2026.
Well‐defined cobalt hydride complexes are versatile catalysts. Two key features of HCo(PMe3)4 are that it promotes highly selective 1,2‐hydroboration of quinolines to form N–B‐substituted 1,2‐dihydroquinolines (1,2‐H‐DHQs) under mild conditions, and that its volatile phosphine ligands and high solubility in pentane enable simple purification, allowing ...

Characterization of Grape Cane Stilbenoids and Their Photo‐Degradation Products by HPLC‐DAD Coupled With Trapped Ion Mobility Spectrometry and High‐Resolution Tandem Mass Spectrometry

Rapid Communications in Mass Spectrometry, Volume 40, Issue 15, 15 August 2026.
ABSTRACT Rationale Bioactive (E)‐stilbenoids in vine extracts are prone to light‐induced transformation into the respective (Z)‐isomers and further degradation products, often resulting in a loss of bioactivity. We sought to study stilbenoid degradation beyond that of the well‐researched resveratrol due to the high diversity of stilbenoids in nature ...
