Electrochemical Hofmann Rearrangement for Modular Synthesis of Unsymmetrical Ureas and Late-Stage Modification of Drugs.

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
Due to the poor compatibility of amines under oxidative conditions and the low chemoselectivity between two different amides, the Hofmann rearrangement of amides involving amine or other amide nucleophiles poses significant challenges. Herein, we present a versatile electrochemical reaction that achieves highly chemoselective Hofmann rearrangement of two different amides with the addition of only sodium iodide, enabling the efficient synthesis of single N-acylureas. Additionally, under similar electrochemical conditions, both primary and secondary amines can also efficiently react with amides to produce unsymmetrical ureas. This electrosynthetic method exhibits good functional group tolerance and has been successfully employed to synthesize five herbicides, as well as to facilitate the late-stage functionalization of over twenty amine-containing drugs. Furthermore, mechanism studies indicated that the use of NaI guaranteed the feasibility and compatibility of the reaction.
