The selenohydrin silanols are versatile synthons (Scheme 7). Oxidation of 4a with Dess-Martin periodinane formed ketone 8 in 52% yield (Scheme 7A). Using acetic anhydride, the C-OH rather than the Si-OH is preferentially transformed into the corresponding acetate (Scheme 7B). We note that 9 (Scheme 7B) contains differentially protected primary and secondary alcohols, a marked advantage of using allylic silanols as starting materials over the analogous allylic alcohols.
