4-Nitrophenyl β-d-apiofuranoside as a chromogenic probe for detection of β-d-apiofuranosidase activity was prepared in 61% yield from 2,3-isopropylidene-α,β-d-apiofuranose through a sequence of five reactions. The synthesis involves one regioselective enzymatic step-benzoylation of primary hydroxyl of 2,3-isopropylidene-α,β-d-apiofuranose catalysed by Lipolase 100T and stereoselective β-d-apiofuranosylation
通过五个反应序列,由2,3-异亚丙基-α,β-d-呋喃呋喃糖以61%的收率制备了4-硝基苯基β-d-呋喃呋喃糖苷作为检测β-d-呋喃糖苷酶活性的生色探针。合成涉及一种由Lipolase 100T催化的2,3-异亚丙基-α,β-d-呋喃呋喃糖伯羟基的区域选择性酶促步骤苯甲酰化和使用BF3·OEt2 / Et3N的对硝基苯酚的立体选择性β-d-呋喃呋喃糖基化。该产物用于筛查61种粗制商业酶和植物材料样品中的β-d-apiofuranosidase活性。源自曲霉属不同菌株的十五种酶制剂显示出β-d-呋喃呋喃糖苷酶活性。在Rapidase AR 2000(78.27 U / g)和冻干的Viscozyme L(64,36 U / g)中发现了最高的活性。
