the deacylation of 4-C-acyloxymethyl-3,5-di-O-acyl-1,2-O-(1-methylethylidene)-beta-L-threo-pentofura nose to form 3,5-di-O-acyl-4-C-hydroxymethyl-1,2-O-(1-methylethylidene)-alpha-D-xylo-pentofura nose in a highly selective and efficient manner. The rate of lipase-catalyzed deacylation of tributanoyl furanose is 2.3 times faster than the rate of deacylation of the triacetyl furanose derivative. In order
Lipozyme TL IM催化4-C-酰氧基甲基-3,5-二-O-酰基-1,2-O-(1-甲基乙叉基)-β-L-苏-五氟呋喃鼻的脱酰基反应以形成3,5-di -O-酰基-4-C-羟甲基-1,2-O-(1-甲基亚乙基)-α-D-木基-五氟呋喃鼻具有高度选择性和高效的方式。脂肪酶催化的三丁酰呋喃糖的脱酰速率比三乙酰基呋喃糖衍生物的脱酰速率快2.3倍。为了确认脂肪酶催化的脱酰产物的结构,将其转化为双环糖衍生物,其可用于合成在开发新型反义和反义寡核苷酸中重要的双环核苷。进一步,
