Removal of the TBS group was accompanied by ethoxide elimination, and we decide to investigate the reactivity of 11 directly. Similar reaction conditions were adopted for free and silyl-protected homoallylic alcohols in the synthesis of blepharocalyxin D; H. M. Ko, D. G. Lee, M. A. Kim, H. J. Kim, J. Park, M. S. Lah, E.

The minor product is presumably epimeric at C3, C5, and C7. For a thorough discussion of the racemization problem in the Prins cyclization, see: R. Jasti, S. D. Rychnovsky, J. Am. Chem. Soc. 2006, 128, 13640-13648.
