Retraction of “Biomimetic Total Synthesis of Himbacine”

This Letter has been retracted, as it was found that (a) spectra of the linear precursor, compound 14, differed when its synthesis was repeated and (b) spectra published for several compounds resulting from compound 14 (compounds 3, 4, and 20) were scanned from other papers. Compounds 3 and 20: Chackalamannil, S.; Davies, R. J.; Asberom, T.; Doller, D.; Leone, D. J. Am. Chem. Soc. 1996, 118 (40), 9812−9813; Chackalamannil, S.; Davies, R. J.; Wang, Y.; Asberom, T.; Doller, D.; Wong, J.; Leone, D.; McPhail, A. T. J. Org. Chem. 1999, 64 (6), 1932−1940. Compound 4: Chackalamannil, S.; Davies, R.; McPhail, A. T. Org. Lett. 2001, 3 (10), 1427−1429.
