Retraction of ‘Organocatalytic stereoselective synthesis of passifloricin A’ by Pradeep Kumar et al., Org. Biomol. Chem., 2012, 10, 1820–1825.
The affected spectra are:
13C NMR spectra for 10, 11, 19, 20, 21 and 22.
1H NMR spectra for 13, 19, 20, 21, 22 and 1.
The Director of the CSIR-National Chemical Laboratory has confirmed that archive copies of some of the original spectra in question have been located and preliminary indication is that there was manipulation of the spectra.
This retraction supersedes the information provided in the Expression of Concern related to this article.
