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

The chemistry of carbohydrates has a history of over 100 years, but simple, stereoselective and efficient glycosylation methods remain highly needed to facilitate the studies of sugars in various disciplines. Here we report a strategy for 1,2-cis-glycosylation without using metals, strong (Lewis) acids, elaborate catalysts or labile substrates. Our method operates by a unique mechanism: it activates glycosyl donors through a radical cascade rather than the conventional acid-promoted, ionic process. As elucidated by computational and experimental studies, the allyl glycosyl sulfones (as donors) form halogen bond complexes with perfluoroalkyl iodides, which-merely by visible light irradiation-fragment via radical intermediates to give the electrophilic glycosyl iodides. In situ trapping by various nucleophiles affords, in a stereoconvergent manner, the challenging 1,2-cis-glycosides. This metal- and acid-free reaction shows remarkable tolerance to functional groups. The high stereoselectivity holds for a broad array of donors. This study suggests that the simple C2-alkoxy group can serve as an effective directing group for building 1,2-cis-glycosidic bonds.
