trihydroxylation and dehydrogenation. The arene hydrates, (R)-1,2-dihydronaphthalen-l-ol 5 and (R)-1,4-dihydronaphthalen-l-ol 7, were isolated as enantiopure metabolites while 1,2-dihydronaphthalen-2-ol 8 was found in almost racemic form. The structure, enantiopurity and absolute stereochemistry of these arene hydrates of naphthalene were confirmed by chemical synthesis. Deuterium labelling studies,
使用恶臭假单胞菌UV4的生长培养物对1,2-和1,4-二氢萘底物进行生物转化,导致双加氧酶催化的苄基单羟基化,顺式-四氢二醇和顺式-二氢二醇的形成,三羟基化和脱氢。芳烃水合物,(R)-1,2-二氢萘-1-醇5和(R)-1,4-二氢萘-1-醇7被分离为对映体纯代谢产物,而1,2-二氢萘-2-醇8几乎呈外消旋形式。这些萘芳烃水合物的结构,对映体纯度和绝对立体化学通过化学合成得到证实。氘标记研究,以及使用对映体纯的芳烃水合物5和7作为底物,用于建立形成(1 R,2 S)-1,2-二氢萘-1,2-二醇2的代谢途径。来自1,2-二氢萘3和1,4-二氢萘6的底物。
