Synthesis of Insect Sex Pheromones by Ligand-Free Iron-Catalyzed Alkyl-Allyl Cross-Coupling Involving α,ω-Difunctionalized Aliphatic Grignard Nucleophiles and Allyl Electrophiles.
Article in ACS omega, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We disclose synthetic access to four insect sex pheromones, proceeding with a key alkyl-allyl disconnection achieved by a ligand-free cross-coupling between α,ω-difunctionalized aliphatic Grignard reagents bearing terminal alkoxides and allylic electrophiles, mediated by an air-stable and inexpensive iron precatalyst. The efficiency of the coupling is ensured by a combination of exo- or endogenous magnesium alkoxide additives and LiCl, enabling appreciable, mild conditions (low 1 mol % catalyst load, noncryogenic temperatures) and proceeding with near-complete stereoselectivity.
