Isothiourea-Catalysed Acylative Kinetic and Dynamic Kinetic Resolution of Planar Chiral Paracyclophanols.
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 4 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 development of synthetic methods for the catalytic enantioselective preparation of planar chiral paracyclophane derivatives is of considerable interest to the synthetic community. To date, relatively few successful and effective organocatalytic approaches to this molecular class have been reported. This manuscript describes effective isothiourea catalysed acylative kinetic (KR) and dynamic kinetic resolution (DKR) approaches to the generation of a range of planar chiral paracyclophane macrocycles with excellent levels of enantioselectivity. Effective KR of configurationally stable planar chiral paracyclophanols with 12- and 13-membered ansa-chains is demonstrated (6 examples, s = up to 50) using 5 mol% of the isothiourea (R)-BTM and isobutyric anhydride. Application to configurationally labile macrocyclic phenols with 14 to 18-membered ansa-chains allows their effective acylative DKR, generating the desired products with excellent enantioselectivity (25 examples, up to 95% yield and 98:2 er).
