The microbiological transformation of the diterpene epicandicandiol (1) with Mucor plumbeus gave foliol (3), sideritriol (5), and 7beta,16alpha,17,18-tetrahydroxy-ent-kaurane (7), while the incubation of candicandiol (2) gave 7alpha,9beta,18-trihydroxy-ent-kaur-16-ene (10), canditriol (11), and 7alpha,16alpha,17,18-tetrahydroxy-ent-kaurane (12). Thus, the main difference observed in both feedings,
用Mucor plumbeus对二萜表烷二二醇(1)进行微生物学转化,得到了叶醇(3),铁三醇(5)和7beta,16alpha,17,18-四羟基-ent-月桂烷(7),同时温育了candicandiol(2)得到7α,9β,18-三羟基ent-kaur-16-ene(10),坎地三醇(11)和7α,16α,17,18-四羟基-ent-kaurane(12)。因此,两种进料中观察到的主要差异是由7-羟基的方向空间变化(从底物1的轴向到赤道的2)导致的,分别是3α-和9β-羟基化衍生物的形成。 。
