Abstract
Expression of Concern for ‘Total synthesis of the natural product EBC-329’ by Raju S. Thombal and Vrushali H. Jadhav, Org. Biomol. Chem., 2015, 13, 9485–9491, https://doi.org/10.1039/C5OB01276G.
Organic & Biomolecular Chemistry is publishing this expression of concern in order to alert readers that we are presently unable to confirm the reliability of the data presented in the article.
There are concerns about the reliability of the NMR spectra in the SI.
The Royal Society of Chemistry has asked the affiliated institution (National Chemical Laboratory (CSIR-NCL)) to investigate this matter and confirm the integrity and reliability of the NMR spectra. An expression of concern will continue to be associated with this manuscript until we receive information from the institution on this matter.
