Sustainable and Scalable Redesign of PS-750-M Synthesis While Retaining Micellar Catalytic Efficiency.
Article in ACS sustainable chemistry & engineering, 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
An efficient, two-step synthetic route for PS-750-M has been developed, offering significant improvements in terms of sustainability, scalability, and operational simplicity compared to the conventional four-step process. The new methodology eliminates hazardous reagents, toxic solvents, and chromatography, while enabling solvent recovery and catalyst reuse. Quantitative green metrics reveal dramatic reductions in environmental impact, with E-factor and Process Mass Intensity (PMI) decreasing by over 90% and 85%, respectively. Importantly, PS-750-M, synthesized via this greener route, retains its micellar catalytic efficiency tested on a variety of transformations, including palladium-catalyzed C-C couplings, Buchwald-Hartwig aminations, biaryl ketone formation, and rapid amide couplings. These results support the industrial viability of the redesigned process and its alignment with the principles of green chemistry, potentially facilitating the large-scale adoption of this approach in pharmaceutical and fine chemical manufacturing.
