A four step degradation of the C8 ethyl ketone of apicidin provided a route to the C6 aldehyde intermediate and several mechanism-based transition state inhibitors of histone deacetylase. The compounds generated herein delineate the significance of apicidin's side chain, highlighted by the high affinity C8 aldehyde and C8-keto-9,10-epoxide analogs of apicidin.
