This thesis describes the total synthesis of (±)-nidemone (1). We used 2-bromo-6-methoxybenzaldehyde 63 as the stating material in the synthesis. The alkyne-ketone 77 was prepared via a Sonogashira coupling of the palladium reagent derived from 62 and 61. Intramolecular stetter cyclization of enone-aldehyde 59 was used to construct the spiro[4.5]decane skeleton. Successive treatment with IBX and BBr3 gave rise to phenol 57, which upon a reaction sequence involving a thio-Michael reaction and NCS oxidation, NaOMe hydrolysis completed the synthesis of (±)-nidemone (1).
