A chemistry journal has issued expressions of concern for three papers after a reader notified the editors of “unexplained discrepancies” in the data.
According to the notices, after the editors of Organic & Biomolecular Chemistry confirmed the problems, they contacted the corresponding author on the three papers, Pradeep Kumar—who works at the Council of Scientific and Industrial Research (CSIR)-National Chemical Laboratory in Pune, India—as well as the director of CSIR, Ashwini Kumar Nangia. The institution conducted its own internal review of the spectra and concluded the authors did not intentionally alter them.
Still, the journal and institution could not confirm the accuracy of the data, and the journal published expressions of concern to warn readers about the issues.
Here’s the expression of concern for “A general and concise asymmetric synthesis of sphingosine, safingol and phytosphingosines via tethered aminohydroxylation:”

All too often, when an article is flagged by a journal that’s concerned about the findings, the notice lingers in limbo, leaving readers unclear whether or not to rely on the findings. One chemistry paper’s two-year stint in purgatory ended last month, when the journal lifted its expression of concern (EOC) and replaced it with a correction.
The journal chose to swap the 2015 EOC with a correction after the authors addressed its concerns in a follow-up paper, also published in Organic & Biomolecular Chemistry.
The journal’s executive editor Richard Kelly provided further insights about what happened:
