Han, B. Y., Lam, N., MacGregor, C. I., Goodman, J., & Paterson, I. (2018). A synthesis-enabled relative stereochemical assignment of the C1-C28 region of hemicalide.. Chem Commun (Camb), 54 (26), 3247-3250. https://doi.org/10.1039/c8cc00933c
Through synthesising both candidate diastereomers of a model C1-C28 fragment of the potent cytotoxic marine polyketide hemicalide, an assignment of the relative configuration between the C1-C15 and C16-C26 regions has been achieved. By detailed NMR comparisons with the natural product, the relative stereochemistry between these two 1,6-related stereoclusters is elucidated as 13,18-syn rather than the previously proposed 13,18-anti relationship. A flexible and modular strategy using an advanced C1-C28 ketone fragment 22 is outlined to elucidate the remaining stereochemical features and achieve a total synthesis.
