[reaction: see text] The microbiological Baeyer-Villiger oxidation of (-)-bicyclo[3.2.0]hept-2-en-6-one allowed exclusive formation of the "unexpected" lactone regioisomer in 84% yield, high chemical purity, and enantiopure form. Substrate (25 g) was transformed in a 1 L bubble column reactor, following a in situ substrate feeding/product removal methodology, which afforded high volumetric productivity
[反应:参见文本](-)-双环[3.2.0] hept-2-en-6-one的微生物学Baeyer-Villiger氧化使得“意外”内酯区域异构体独家形成,产率为84%,化学纯度高和对映纯形式。按照原位底物进料/产品去除方法,将底物(25 g)在1 L鼓泡塔反应器中进行转化,该方法可提供高体积生产率(1.2 g L(-)(1)h(-)(1))。这说明了这种方法的高度“可持续化学”优点,该方法简单地在水性介质中,在室温和使用大气氧气的条件下进行。
