  日期：2016.5

  Amido-substituted Malonic Acid Half Oxyesters (MAHOs) have proven to be excellent partners of various aromatic aldehydes in the presence of secondary amine, trifluoromethanesulfonic acid to perform a Knoevenagel–Doebner condensation under mild conditions with good to excellent yields. A mechanistic study revealed that the sequence involved the formation of an iminium intermediate to provide stereoselectively Z-α,β-unsaturated

• Indirect electrochemical α-methoxylation of -acyl and -carboalkoxy α-amino acid esters and application as cationic glycine equivalents
  作者：Klaus-Dieter Ginzel、Peter Brungs、Eberhard Steckhan

  DOI：10.1016/s0040-4020(01)80034-x

  日期：1989.1

  Indirect electrochemical methoxylation of -acyl and -carboalkoxy α-amino acid esters in α-position to nitrogen is possible, if chloride is used as mediator. The course of the reaction depends upon the protecting group as well as upon the amino acid side-chain. Increased electron withdrawing effects of the protecting group are accelerating the reaction. On the other hand aliphatic side-chains are diminishing

  如果使用氯化物作为介体，则可以在α位上将-酰基和-羰基烷氧基α-氨基酸酯间接电化学甲氧基化为氮。反应过程取决于保护基以及氨基酸侧链。保护基团的吸电子作用增强，促进了反应。另一方面，脂族侧链降低了反应性。高氯离子浓度提高了电流产量，令人惊讶地强。

  highly carbon‐selective difluoromethylation of soft carbon nucleophiles including β‐ketoesters, malonates, oxindoles, benzofuranones and ketene silyl acetals with a difluoromethylated sulfonium ylide under mild conditions was described. Mechanistic studies suggest that these difluoromethylating reactions proceed via a difluorocarbene pathway.

  A copper-catalyzed annulation of oxime acetates and α-amino acid ester derivatives for the easy preparation of 4-pyrrolin-2-ones bearing a 3-amino group has been developed. This process features the oxidation of amines with oxime esters as the internal oxidant to produce the active 1,3-dinucleophilic and 1,2-dielectrophilic species concurrently.
