Hexacyclinol Retracted. It Only Took Six Years.
Via Chemjobber's Twitter feed comes news of this: the formal retraction of the LaClair hexacyclinol synthesis.
The retraction has been agreed due to lack of sufficient Supporting Information. In particular, the lack of experimental procedures and characterization data for the synthetic intermediates as well as copies of salient NMR spectra prevents validation of the synthetic claims. The author acknowledges this shortcoming and its potential impact on the community
Potential? After six years? There were people taking their first undergraduate organic course when this controversy hit who are now thinking about how to start tying together their PhD dissertations. It seems that Angewandte Chemie is very loath to go the full-retraction route (there haven't been many), but that retraction notice doesn't bring up anything that wasn't apparent after the first ten minutes of reading the paper.
Update: Wavefunction isn't too impressed, either.
