This involved a porcine pancreatic lipase (PPL)-catalyzed delta-lactonization of a racemic 3,5-dihydroxy-2-alkyl ester to produce the lactone with high enantioselectivity (92.8%). The product lactone and its analogues are useful synthons for the asymmetric synthesis of various bioactive compounds, which include the potential anti-obesity compound, tetrahydrolipstatin.
已经制定了一种新颖的脂肪酶催化方案,用于在柔性无环系统中同时控制三个立体生成中心。这涉及猪胰脂肪酶(PPL)催化的外消旋3,5-二羟基-2-烷基酯的δ-内酯化,以产生具有高对映选择性(92.8%)的内酯。内酯产物及其类似物是有用的合成子,用于各种生物活性化合物的不对称合成,其中包括潜在的抗肥胖化合物四氢脂肪抑制素。
