the first biocatalytic modification of sesquiterpenelactones (STL) found in chicory plants. Regioselective O-acylation of their primary alcohol group is achieved by the immobilized lipase B from Candida antarctica, with various aliphatic vinyl esters as acyl donors. High conversion rates were observed, facilitating the synthesis of novel semi-synthetic STL ester derivatives with promising pharmaceutical
本文报道了在菊苣植物中发现的倍半萜内酯 (STL) 的首次生物催化修饰。其伯醇基团的区域选择性O-酰化是通过来自南极假丝酵母的固定化脂肪酶 B 以各种脂肪族乙烯基酯作为酰基供体实现的。观察到高转化率,促进了具有良好药物应用前景的新型半合成STL酯衍生物的合成。
