Ligand Type Guided Keto-Arylation Enables Modular Total Synthesis of Polycyclic CBS Xanthones.
Article in Angewandte Chemie (International ed. in English), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The first total synthesis of the potent polycyclic xanthone antibiotics CBS72, CBS87 and CBS100 was accomplished by a modular strategy featuring a very demanding intermolecular aromatic keto-arylation. Central to the solution was a recently-developed ligand type approach, rather than brute force screening, demonstrating the usefulness of this novel concept in complex target synthesis. Additional key features include an asymmetric Davis hydroxylation proceeding with only catalytic amounts of base, thus enabling the conversion of a highly sensitive, elaborate substrate. Furthermore, a late-stage aminolysis completed the polycyclic framework, circumventing laborious protective group chemistry. Together, this strategy provides a concise, high-yielding access, confirming the full architecture of this most potent class of polyaromatic xanthones, and establishes ligand types as a powerful design tool for sophisticated cross-couplings.
