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.

Lipase-Catalyzed Transesterification of 2-Hydroxy-2-(pentafluorophenyl)acetonitrile Leading to (1R,2R)- and (1S,2S)-Bis(pentafluorophenyl)ethane-1,2-diol

, 2016
Optically pure (1R,2R)- and (1S,2S)-1,2-bis(pentafluorophenyl)ethane-1,2-diol (1) were synthesized from key intermediates (R)- and (S)-2-hydroxy-2-(pentafluorophenyl)acetonitrile (2), both of which were prepared by the lipase LIP-catalyzed ...

Building Blocks for Acetylenic Scaffolding Inspired by 6,6,12‐Graphyne

European Journal of Organic Chemistry, Volume 29, Issue 32, 24 August 2026.
6,6,12‐Graphyne is an elusive allotrope of carbon. Here, we present the synthesis and properties of a selection of useful molecular building blocks to advance the preparation of various segments of 6,6,12‐graphyne. These modules are derived from tri‐ and tetraethynylethene derivatives, di‐ and tetraethynyl‐substituted tolane derivatives, as well as ...

Lewis‐Acidic Properties and Catalytic Behavior of Hydroboration‐ and Diolysis‐Derived NHC‐Stabilized Borenium Cations

Chemistry – A European Journal, Volume 32, Issue 31, 18 August 2026.
A series of thirteen (N‐heterocyclic carbene) NHC‐stabilized borenium cations is synthesized from NHC→BH3 complexes via hydroboration and condensation with diols. The novel compounds are fully characterized. Eight crystal structures are presented. Kinetic and NMR data show how the structural features translate to catalytic activity in hydrosilylation ...

Isomer-specific metabolism and novel metabolite identification of bisphenol A and its isomer o, p’-BPA in humans

Ecotoxicology and Environmental Safety
Studies have identified bisphenol A (BPA) and its isomer o, p’-BPA in environmental and human samples, indicating their potential risks to human health. Yet, the risks of their co-exposure cannot be extrapolated from individual profiles, as interactions ...

Towards sympathetic cooling of large molecules: Cold collisions between benzene and rare gas atoms [PDF]

, 2009
This paper reports on calculations of collisional cross sections for the complexes Z-CDH6 (X = 3He, 4He, Ne) at temperatures in the range 1)μK - 10K and shows that relatively large cross sections in the 103-105Å2 range are available for collisional ...
