Enantioselective Borylcupration/Cyclization of Alkene-Tethered Oxime Esters.
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 1 paper.
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 copper-catalyzed enantioselective synthesis of borylated 1-pyrrolines from γ,δ-unsaturated oxime esters is reported. Twenty-four novel 1-pyrroline derivatives are reported in yields ranging from 26% to 96% and enantioselectivities from 74.5:25.5 er to 99:1 er. Examples derived from α-unsubstituted, non-fluorinated oxime esters are reported. The hydroxyl group following oxidation of the Bpin moiety acts as a directing group in highly diastereoselective reductions of the pyrrolines to the corresponding prolinol derivatives. Additionally, the Bpin group can be retained in the products following a simplified, chromatography-free workup procedure. DFT supports a reaction mechanism which proceeds through the formation of an (R)-benzylic copper intermediate, followed by stereoretentive cyclization with respect to the configuration at the metalated carbon. The conclusions of the computational data are corroborated through control experiments and deuterium-labelling studies.
