Overview of Photochemical Reactions for the Synthesis of Aza and Oxa-Spirocyclic Compounds Under Visible Light Irradiation.
Review in Chemistry & biodiversity, 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
Photochemical reactions play a significant role in organic transformation, the synthesis of natural products, and the development of advanced materials. This elegant approach has been widely explored for the construction of biologically active architectures that are often difficult to access through conventional thermal methods. Spirocyclic compounds represent an important class of compounds found in various approved drug candidates. This review summarizes the myriad photochemical reactions, particularly the visible-light-driven synthesis of aza, oxa, and aza-oxa spirocyclic compounds, reported during the periods 2015-2025. Most of the reactions discussed in this review are one-pot synthetic approaches to access the desired spirocyclic product with excellent yield and regioselectivity. Overall, this review highlights the significance of photochemical methods as powerful tools for the sustainable construction of natural and synthetic spirocyclic scaffolds.
