β-Quaternary α-Amino Acids via Iridium-Catalyzed Branched and Enantioselective Hydroalkylation of 1,1-Disubstituted Styrenes.
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 3 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
A cationic Ir(I)-complex modified with the chiral diphosphine DM-SEGPHOS mediates the hydroalkylation of diverse α-methyl styrenes with N-aryl glycine derivatives. The processes occur with complete branched selectivity and high enantioselectivity. Styrenes possessing higher α-alkyl substituents also participate to provide the targets with moderate to excellent levels of diastereoselectivity. The products are readily advanced to β-quaternary α-amino acids that are inaccessible or cumbersome to access by other means. In broader terms, the study demonstrates how catalyst controlled C─H additions across alkenes can be used to execute the by-product-free construction of contiguous acyclic trisubstituted and quaternary centers.
