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

"Click organocatalysis" uses mutually orthogonal click reactions to organocatalyze a click reaction. We report the development of an isobenzofuran organocatalyst that increases the rate and regioselectivity of an azide-alkyne cycloaddition. The organocatalytic cycle consists of (1) a Diels-Alder reaction of an alkyne with a diarylisobenzofuran to form a benzooxanorbornadiene, (2) a 1,3-dipolar cycloaddition with an azide to form a 4,5-dihydro-1,2,3-triazole, and (3) a retro-Diels-Alder reaction that releases the triazole product and regenerates the diarylisobenzofuran organocatalyst. The diarylisobenzofuran organocatalyst was computationally designed to catalyze the reaction of perfluorophenyl azide and methyl propiolate to selectively form a 1,4-triazole product. Experimental validation of the designed organocatalyst was obtained with methyl 4-azido-2,3,5,6-tetrafluorobenzoate and methyl propiolate.
