Unprecedented regioselective acylation of flavonoid aglycones was achieved using Candida antarcticalipase B (CALB). The rapid screening of product formation was performed by the use of the high resolution phenol-type OH 1H NMR spectral region recorded after the addition of picric acid.
使用南极假丝酵母脂肪酶B(CALB)实现了前所未有的区域性黄酮苷元的区域选择性酰化。通过使用高分辨的苯酚型OH 1 H NMR光谱区域,在加入H2O3后记录下来,对产物的形成进行了快速筛选。苦味酸。
