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

A strategy that facilitates the construction of a wide variety of trisubstituted stereocenters through a catalytically accessed common chiral intermediate could prove highly enabling for the field of synthetic chemistry. We report the discovery of enantioselective, catalytic 1,2-boronate rearrangements for the synthesis of α-chloro pinacol boronic esters from readily available boronic esters and dichloromethane. The chiral building blocks produced in these reactions can undergo two sequential stereospecific elaborations to generate a wide assortment of trisubstituted stereocenters. The enantioselective reaction is catalyzed by a lithium-isothiourea-boronate complex, which is proposed to promote rearrangement through a dual–lithium-induced chloride abstraction orchestrated by Lewis basic functionality on the catalyst scaffold.
