  Synthesis of Alkyl (�)-2,3-Di-O-acylglycerates and Attempts Directed to their Conversion into Alkyl (R)-2,3-Di-O-acylglycerates by Enzyme-catalyzed Enantioselective Deacylation Reactions [1]

  摘要：

  By screening several lipases and proteases as catalysts for an enantioselective partial deacylation of methyl (+/-)-2,3-di-O-acylglycerates, it was found that methyl (R)-2,3-di-O-butanoylglycerate can be obtained with an enantiomeric excess of >96% and a yield of 20% related to the racemic starting material. This was prepared from methyl acrylate through dihydroxylation with potassium permanganate at -30-degrees-C and a subsequent bisacylation.

  An aluminum compounds represented by the following general formula (1): Al(R1—SO3)1(R2)m(R3)n   (1) wherein R1 is a hydrocarbon group which may be substituted, R2 is a hydrocarbon group which may be substituted, an aliphatic hydrocarbonoxy group which may be substituted, or a halogen atom, R3 is an aromatic hydrocarbonoxy group which may be substituted, and 1, m and n are independently a number of 0 to 3, with the proviso that 1+m+n equals 3, and 1 is not 0, an acid catalyst comprising the aluminum compound, and a process for producing an ester, acetal, ketal, ether or alkyl glycoside making use of the catalyst. The catalyst is suitable for use in a variety of acid-catalyzed reactions of alcohols, i.e., reactions with carbonyl compounds, such as esterification, transesterification, acetalization and ketalization, etherification, ring-opening reactions of epoxy compounds, etc. in addition to the above-described respective reactions, is not deactivated by alcoholysis, has a sufficient activity, can easily control a reaction catalyzed thereby and scarcely causes side reactions. Consequently, the use of the catalyst permits the production of the intended product at a high yield from starting materials used in an almost equimolar proportion.

  铝化合物的一般公式（1）表示为：Al（R1—SO3）1（R2）m（R3）n（1），其中R1是一个可能被取代的碳氢基团，R2是一个可能被取代的碳氢基团，一个可能被取代的脂肪烃氧基团，或者一个卤素原子，R3是一个可能被取代的芳香烃氧基团，1、m和n分别是0到3的数字，但1、m和n之和等于3，并且1不等于0，包括铝化合物的酸催化剂，以及利用该催化剂制备酯、缩醛、缩酮、醚或烷基糖苷的方法。该催化剂适用于醇的各种酸催化反应，即与羰基化合物的反应，如酯化、酯交换、缩醛化和缩酮化、醚化、环氧化合物的开环反应等。除了上述各种反应外，该催化剂不会被醇解激活，具有足够的活性，可以轻松控制其催化的反应，几乎不会引起副反应。因此，使用该催化剂能够从几乎等摩尔比例的起始原料中高产率地生产预期产品。
