Substitutive Approach Toward Heteroaromatic Amino Alcohols Accessed Through Dioxolanyl Radical Linchpin.
Article in Advanced synthesis & catalysis, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Aryl ethanolamines are an important functional group found in a variety of pharmaceuticals and natural products. For the past century, the main strategies for synthesizing these compounds are through Henry reactions followed by reductions or olefin oxidations using aldehyde or styrene starting materials. Herein, we disclose a highly adaptable synthesis of heteroaromatic amino alcohols enabled by a dioxolanyl radical linchpin strategy to take advantage of highly abundant aryl bromides and complex amine precursors. This methodology has been demonstrated across a variety of substrates, including a diverse set of thirteen distinct heteroarene classes. After mild deprotection, these diols can be simply activated and functionalized for chemoselective amino alcohol formation. The chosen retrosynthetic disconnection allows the incorporation of commercially available amines directly in synthesis.
