This study explored the substrate scope and regio-selectivity of Gliocladium deliquescens NRRL 1086 on hydroxylated benzophenones (HBPs), which was the follow-up investigation on the glycosylation of phenolic hydroxyl compounds by this unique microbe. Five HBPs substrates were used and three glycosylated metabolites, iriflophenone 2-O-β-d-glycopyranoside (6, 40%), riflophenone 4-O-β-d-glycopyranoside(7
本研究探讨的底物范围和区域选择性粘帚deliquescens NRRL 1086上羟基化的二苯甲酮(HBPS),这是通过这个独特的微生物上的酚羟基的化合物的糖基化的后续调查。使用五个HBPS衬底和三个糖基化的代谢产物,iriflophenone 2- ö - β -D- glycopyranoside(6,40%),4- riflophenone ø - β -D- glycopyranoside(7,21%)和2,6,4'三羟基-4-甲氧基-2- ø - β -D- glycopyranoside(8,65%)进行分离和结构上由ESI-MS,明确地识别11 H NMR,13 C NMR和2D NMR光谱。的糖基化多功能能力G. deliquescens上酚羟基的化合物1086 NRRL可提供可选的和方便的方法,以使各个HBPS苷的高效合成。
