Procedure: In a manner similar to that set forth in A, but substituting for acetic anhydride, the anhydrides or halides of propionic, butanoic, pentanoic, or hexanoic acid, the corresponding manoalide δ-lactone propionate, butanoate, pentanoate, and hexanoate are prepared.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: This dione was prepared by the acid cyclization of ethyl 6-(3'chlorophenyl)-6-cyano-5-keto-3,3-dimethylhexanoate. Preparation of the hexanoate is described in Part A and of the dione in Part B below.
