  Enantiomerically pure tetrahydro-5-oxo-2-furancarboxylic esters from dialkyl 2-oxoglutarates

  摘要：

  Enantiomerically pure tetrahydro-5-oxo-2-furancarboxylic esters can be prepared either by enzymatic resolution of the racemic gamma-lactones themselves or by bioreduction with baker's yeast of dialkyl 2-oxoglutarates and subsequent cyclization of the resulting dialkyl 2-hydroxyglutarates. The best results were obtained by the former route, by which the desired compounds were isolated in high enantiomeric excess. Bioreductions were less satisfactory. In fact the hydroxyester intermediates were initially formed as racemic mixtures and their final enantiomeric enrichment was reached by asymmetric destruction, occurring in the bioreaction medium, however at the same time large amounts of alkyl 4-hydroxybutanoates were formed as side products.

• Lactonization of the Oncometabolite D-2-Hydroxyglutarate Produces a Novel Endogenous Metabolite

  In recent years, onco-metabolites like D-2-hydroxyglutarate, which is produced in isocitrate dehydrogenase-mutated tumors, have gained increasing interest. Here, we report a metabolite in human specimens that is closely related to 2-hydroxyglutarate: the intramolecular ester of 2-hydroxyglutarate, 2-hydroxyglutarate-γ-lactone. Using 13C5-L-glutamine tracer analysis, we showed that 2-hydroxyglutarate is the endogenous precursor of 2-hydroxyglutarate-lactone and that there is a high exchange between these two metabolites. Lactone formation does not depend on mutated isocitrate dehydrogenase, but its formation is most probably linked to transport processes across the cell membrane and favored at low environmental pH. Furthermore, human macrophages showed not only striking differences in uptake of 2-hydroxyglutarate and its lactone but also in the enantiospecific hydrolysis of the latter. Consequently, 2-hydroxyglutarate-lactone may play a critical role in the modulation of the tumor microenvironment.

  近年来，像D-2-羟基戊二酸这样的肿瘤代谢产物，它是在异柠檬酸脱氢酶突变肿瘤中产生的，引起了越来越多的关注。在这里，我们报告了人体标本中与2-羟基戊二酸密切相关的一种代谢产物：2-羟基戊二酸的分子内酯，2-羟基戊二酸-γ-内酯。使用13C5-L-谷氨酰胺示踪分析，我们表明2-羟基戊二酸是2-羟基戊二酸内酯的内源前体，并且这两种代谢产物之间存在高度交换。内酯的形成并不依赖于突变的异柠檬酸脱氢酶，但其形成很可能与细胞膜之间的转运过程有关，并且在低环境pH下更为有利。此外，人类巨噬细胞不仅在对2-羟基戊二酸及其内酯的摄取上存在显著差异，而且在对后者的对映选择性水解上也存在差异。因此，2-羟基戊二酸内酯可能在调节肿瘤微环境中发挥关键作用。

• LiNTf₂-Catalyzed Aminolysis of Lactones with Stoichiometric Quantities of Amines
  作者：Antonio Guarna、Claudia Lalli、Andrea Trabocchi、Gloria Menchi

  DOI：10.1055/s-2007-1000882

  日期：2008.1

  LiNTf2 in the reaction of lactones with amines is able to activate cyclic esters towards ring opening, thus leading to clean open-chain amides under mild conditions and using a stoichiometric amount of amine. The generality of the method was demonstrated by a range of selected lactones and amines.
