Rearrangement of the decalin system of pravastatin under S N 2 0 Mitsunobu conditions and subsequent selective hydrolysis and oxidation afforded a key dienone 23, which upon copper-catalyzed addition of a 1E-propenyl moiety established the carbon framework of BB-476 3 in high diastereomeric excess.
