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

Dalesconols A and B, featuring unique and highly congested polycyclic carbon frameworks and notable biological activities, have attracted sustained attention. However, their structural complexity constitutes a significant challenge for total synthesis. Herein, we present the asymmetric total syntheses of (+)-dalesconols A and B via a remote chirality transfer strategy. Central to this approach is the implementation of our palladium/norbornene-catalyzed trifunctionalization method, which enables one-step construction of the chiral polycyclic core skeleton via a triple relay of point-to-axial, axial-to-axial, and axial-to-point chirality transfer. Combined with intramolecular Michael addition, C-H oxidation/retro-Michael elimination, and global demethylation, this triple-relayed remote chirality transfer strategy allows concise and modular access to (+)-dalesconols A and B.
