Biotransformation of acridine, dictamnine and 4-chlorofuro[2,3-b]quinolone, using whole cells of Sphingomonas yanoikuyae B8/36, yielded five enantiopure cyclic cis-dihydrodiols, from biphenyl dioxygenase-catalysed dihydroxylation of the carbocyclic rings. cis-Dihydroxylation of the furan ring in dictamnine and 4-chlorofuro[2,3-b]quinoline, followed by ring opening and reduction, yielded two exocyclic
yan啶鞘氨醇单胞菌B8 / 36的全细胞对a啶,三氢嘧啶和4-氯呋喃并[2,3- b ]喹诺酮进行生物转化,由联苯双加氧酶催化的碳环的二羟基化反应产生了五个对映体纯的环状顺式-二氢二醇。胺和4-氯呋喃并[2,3- b ]喹啉中呋喃环的顺式-二羟基化,然后开环还原,生成了两种环外二醇。代谢物的结构和绝对构型已通过光谱学和立体化学相关方法确定。从相应的顺式合成了a啶和三氢萘胺的对映体纯的氧化芳烃代谢物-二氢二醇。非手性呋喃喹啉生物碱强健碱,γ-甘氨酸,单倍体,异单倍体3,3'-二甲基烯丙基醚和蝶呤已从顺苯二胺的顺式-二氢二醇,儿茶酚或氧化芳烃代谢物获得。
