K. M. Chen, G. E. Hardtmann, K. Prasad, O. Repic, M. J. Shapiro, Tetrahedron Lett. 1987, 28, 155-158. Reduction of hydroxyenone 11 using conditions reported in the reference above (Et 2BOMe, NaBH4) gave the 1,3-syn diol as a single diastereomer on a small scale. On larger scales, this transformation was accompanied by partial cleavage of the C23 and C31 protecting groups during workup. Fortunately, both of these groups must be removed in the next step to give our desired C22-C33 ketone intermediate 2. In practice, treatment of the mixture of partially deprotected compounds with FeCl3 in dry acetone containing desispheres resulted in complete desilylation, benzodioxepine removal, and acetonide installation to afford 2 in good yield 68, 2 steps

Compound 13 is prone to hydration and polymerization. We have found this polymerization to be reversible and that the bisaldehyde can be obtained by dehydration see the Supporting Information for details, For a similar observation and transformation, reported while this work was in progress, see: J.
