Exploring Isophorone‐Based Dienones: Comprehensive Insights Into Their Synthesis, Reactivity, and Diverse Applications

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
Isophorone is an important motif in synthetic organic chemistry, as it is highly reactive and can get involved in a diverse array of functional group transformations to access various synthetic intermediates and molecular targets. In this context, an important group of compounds is the conjugated or nonconjugated isophorone‐cored dienones, which are ...

Metabolomic and transcriptomic data on major metabolic/biosynthetic pathways in workers and soldiers of the termite Prorhinotermes simplex (Isoptera: Rhinotermitidae) and chemical synthesis of intermediates of defensive (E)-nitropentadec-1-ene biosynthesis

open access: yesData in Brief, 2018
Production of nitro compounds has only seldom been recorded in arthropods. The aliphatic nitroalkene (E)-nitropentadec-1-ene (NPD), identified in soldiers of the termite genus Prorhinotermes, was the first case documented in insects in early seventies ...

Catalytic Strategies for Amide‐Based Michael Additions: Advances and Perspectives

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
The Michael addition is a cornerstone transformation in organic synthesis, enabling efficient C–C and C–heteroatom bond formation. Traditionally, α,β‐unsaturated carbonyl compounds such as enones and esters have dominated as Michael acceptors, whereas α,β‐unsaturated amides remain underutilized due to their strong resonance stabilization and low ...
