chromophore OC.C(Br) CH.C and at position 3 by the formation of a seco-acid containing the grouping CH2C.(CH3). The 16α-hydroxyl stereochemistry is confirmed by its formation from 3α-hydroxy- and 3-oxo-(—)-kaur-16-ene.
通过形成含有发色团OCC(Br)CH.C的
溴化α-β-不饱和酮,使abbeokutone的羰基位于环A上,并通过形成含有CH基团的
癸二酸而将其定位在3位上。2 C。(CH 3)。通过从3α-羟基-和3-氧代-(-)-kaur-16-烯的形成证实了16α-羟基立体
