  Baker's yeast mediated stereoselective biotransformation of 1-acetoxy-3-aryloxypropan-2-ones

  摘要：

  A series of 1-acetoxy-3-aryloxypropan-2-ones la-m were synthesized and subjected to biotransformation by baker's yeast yielding optically active monoacetates 5 or ent-5 and/or diols 4 of moderate to excellent enantiomeric purity. The dependence of the reduction/hydrolysis ratio and stereoselectivity on the size and substitution pattern of the aromatic moiety in the substrate is also discussed. (C) 1998 Elsevier Science Ltd.

• Efficient resolution of 3-aryloxy-1,2-propanediols using CLEA-YCJ01 with high enantioselectivity

  The lipase YCJ01 from Burkholderia ambifaria is an organic solvent-stable enzyme and its activity can be activated by a hydrophobic solvent due to the “interface activation” mechanism. The activity of lipase YCJ01 increased by 2.1-fold with t-butanol as the precipitant even after cross-linking. The cross-linked enzyme aggregates of lipase YCJ01 (CLEAs-YCJ01) were found to be efficient for resolving

  来自Burkholderia ambifaria的脂肪酶YCJ01是一种有机溶剂稳定的酶，由于“界面激活”机制，其活性可以被疏水性溶剂激活。以叔丁醇为沉淀剂，脂肪酶YCJ01交联后活性仍提高2.1倍。研究发现，脂肪酶 YCJ01 的交联酶聚集体 (CLEAs-YCJ01) 可通过顺序酯化有效分解 3-(4-甲基苯氧基)-1,2-丙二醇 (MPPD)。使用高底物浓度（180 mmol L-1）实现了对 MPPD 的优异对映选择性（E > 400），S-二乙酸盐的对映体过量 (ee) 值高达 99.2%， R-单乙酸盐的对映体过量 (ee) 值为 99.1% ，并且产率很高 (49.9%) −1 )。由此，同时获得了具有优异ee值的R型和S型化合物，并且通过CLEAs-YCJ01解决了MPPD。CLEAs-YCJ01还表现出较高的操作稳定性，十批次后仍保持91.2%的残留活性。为了进一步评估 CLEAs-YCJ01

  The kinetic resolution of 13 racemic aliphatic 1,2-diols (rac-1a-m) by means of a lipase-catalyzed sequential acetylation was investigated. The enantioselectivity of the 3-aryloxy-propane-1,2-diols rac-1a-k depends on the substitution pattern at the aryl ring.
• Kinetic resolution of acyclic 1,2-diols using a sequential lipase-catalyzed transesterification in organic solvents

  A method for the kinetic resolution of 3-(aryloxy)-1,2-propanediols rac-1a-n without additional protection-deprotection steps using a lipase-catalyzed sequential transesterification with lipase amnno PS has been developed. In the first step of this one-pot procedure the racemic 1,2-diols are acylated regioselectively at the primary hydroxy group without enantioselection. The subsequent acylation at the secondary hydroxy group of the formed primary monoacetate is responsible for high enantioselection. The enantioselectivity of this transformation depends significantly on the substitution pattern of the aryl ring and the organic solvent used. 3-(Aryloxy)-1,2-propanediols with substituents in the para-position show a much higher enantioselectivity than the corresponding derivatives with ortho-substituents. Among other substrates, the pharmaceuticals Mephenesin, Guaifenesin, and Chlorphenesin have been resolved. The replacement of the aryloxy by alkyl substituent causes a dramatic decrease of enantioselectivity.
