the decalin system of pravastatin under SN2′ 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.
普伐他汀的萘烷体系在S N 2'Mitsunobu条件下的重排以及随后的选择性水解和氧化反应产生了关键的二烯酮23,该二烯酮在铜催化下添加1 E-丙烯基部分后,在高浓度下建立了BB-476 3的碳骨架。非对映体过量。
