1 · What the graph read from it

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.

2 · The registry

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

While copper-catalyzed asymmetric propargylic substitution has emerged as a versatile tool for constructing chiral propargylic frameworks, its application in forging cyclic chiral quaternary carbon centers remains a significant synthetic challenge. This work demonstrates a dinuclear copper-catalyzed asymmetric [3 + 2] annulation strategy between tertiary propargyl carbonates and diverse C,O-bisnucleophiles under mild conditions. The protocol enables efficient synthesis of chiral dihydrofurans featuring cyclic quaternary stereocenters with broad substrate compatibility. The stereochemical control may arise from the unique coordination geometry of dinuclear copper-allenylidene intermediates, which spatially aligns the electrophilic site within the chiral ligand environment. This spatial arrangement overcomes inherent steric challenges in the stereoselective formation of quaternary carbons bearing dual alkyl substituents, offering mechanistic insights into cooperative dinuclear catalysis for asymmetric transformations.
