摘要:
Steroids containing a cyclohexene moiety are efficiently oxidized to the corresponding α, β-unsaturated ketone using copper iodide and t-butyl hydroperoxide. A steroid compound containing the α, β-unsaturated ketone structure is efficiently converted to the corresponding vicinal diol using a hydroborating reagent followed by oxidative workup, e.g., borane followed by sodium perborate. Benzoyl and substituted benzoyls are superior protecting groups for hydroxyl groups present in the compounds.

摘要:
The present invention is directed to a method for reducing the emetogenic effects of PDE inhibitors, and more particularly is directed to compounds having PDE4 inhibition activity with little or no emetogenic side-effects, and chemical methods including benzylation for preparing such compounds. A benzyl group may be attached to either a carbon or nitrogen atom of a PDE4 inhibitor. Suitable benzylation chemistry is to extract a hydrogen from a PDE4 inhibitor, preferably with a base, and then react the resulting nucleophilic PDE4 inhibitor with a benzylating agent, e.g. benzyl bromide or a derivative thereof.
