  描述了一种新颖的两步程序，用于将甲酯酯碳均一化为酯，硫代酯，羧酸和酰胺。使甲酯与氯甲基苯基亚砜的碳负离子锂反应，以70％至90％的收率得到α-氯代α-亚磺酰基酮。在-78°C下用叔丁基锂处理α-氯代α-亚磺酰基酮的烯醇钾，以通过亚烷基类胡萝卜素生成炔醇。将该中间体用醇，硫醇，5％NaOH水溶液和胺盐酸盐处理，分别以良好或优异的收率得到一碳均酸酯，酯，硫代酸酯，羧酸和酰胺。

  A new metallo-β-lactamase inhibitor which acts as a medicament for inhibiting the inactivation of β-lactam antibiotics and recovering anti-bacterial activities is disclosed. The maleic acid derivatives having the general formula (I) have metallo-β-lactamase inhibiting activities. It is possible to recover the anti-bacterial activities of β-lactam antibiotics against metallo-β-lactamase producing bacteria by combining the compound of the general formula (I) with β-lactam antibiotics.

  Although diazomethane is used in the Arndt-Eistert synthesis, it is both highly toxic and also explosive, and hence should be very carefully handled. In place of this hazardous diazomethane, stable and safe trimethylsilyldiazomethane (TMSCHN2) was found to be very useful for the Arndt-Eistert synthesis. TMSCHN2 was easily acylated with a carboxylic acid chloride in tetrahydrofuran-acetonitrile, and thermal treatment of the acylated product in benzyl alcohol and 2, 4, 6-trimethylpyridine smoothly gave the benzyl ester of a homologated acid. Nucleophiles other than benzyl alcohol could also be used. TMSCHN2 may also be able to replace diazomethane in other areas of chemistry.

  尽管偶氮甲烷在阿恩特-艾斯特合成中使用，但它具有高毒性和爆炸性，因此应该非常小心地处理。为了替代这种危险的偶氮甲烷，稳定且安全的三甲基硅烷偶氮甲烷（TMSCHN₂）被发现对于阿恩特-艾斯特合成非常有用。TMSCHN₂可以在四氢呋喃-乙腈中与卤代羧酸酰氯轻松进行酰化，酰化产物在苄醇和2,4,6-三甲基吡啶中的热处理顺利得到了一种同 homologated acid 的苄酯。除了苄醇之外，其他亲核试剂也可以使用。TMSCHN₂可能还能够替代偶氮甲烷在其他化学领域的应用。

  The invention provides compounds and methods, for example, to carry out organocatalytic Michael additions of aldehydes to cyclically constrained nitroethylene compounds catalyzed by a pro line derivative to provide cyclically constrained α-substituted-γ-nitro-aldehydes. The reaction can be rendered enantioselective when a chiral pyrrolidine catalyst is used, allowing for Michael adducts in nearly optically pure form (e.g., 96 to >99% e.e.). The Michael adducts can bear a single substituent or dual substituents adjacent to the carbonyl. The Michael adducts can be efficiently converted to cyclically constrained protected γ- amino acid residues, which are essential for systematic conformational studies of γ-peptide foldamers. New methods are also provided to prepare other γ-amino acids and peptides. These new building blocks can be used to prepare foldamers, such as α/γ-peptide foldamers, that adopt specific helical conformations in solution and in the solid state.

  该发明提供了化合物和方法，例如，用于催化贝氏碱衍生物对环状约束硝基乙烯化合物进行醛的有机催化Michael加成，从而提供环状约束的α-取代-γ-硝基醛。当使用手性吡咯烷催化剂时，反应可以实现对映选择性，从而以几乎光学纯形式（例如，96%至>99% e.e.）获得Michael加合物。Michael加合物可以在羰基相邻处携带单取代基或双取代基。Michael加合物可以高效转化为环状约束的保护γ-氨基酸残基，这对于γ-肽折叠体系的系统构象研究至关重要。还提供了制备其他γ-氨基酸和肽的新方法。这些新的构建模块可用于制备折叠体，例如α/γ-肽折叠体，在溶液中和固态中采用特定螺旋构象。
