    • Although a similar reaction sequence could be accomplished from 19 to give the silyl ether analogue of 23, the mixture of diastereomers could not be efficiently separated.

    • Relative and absolute configuration of 23 was confirmed by X-ray diffraction analysis of the secondary alcohol resulting from DDQ oxidative removal of the p-methoxybenzyl ether protective group. Please see Supporting Information for details.

    • Iodocyclization of the tert-butyl carbonate derivative of the alcohol of 38 was successful. However radical deiodination resulted in a product attributed to radical cyclization onto the C28-C29 alkene. Please see Supporting Information for more discussion.
