  A Simple Primary Amine Catalyst for Enantioselective α-Hydroxylations and α-Fluorinations of Branched Aldehydes

  摘要：

  A new primary amine catalyst for the asymmetric a-hydroxylation and a-fluorination of alpha-branched aldehydes is described. The products of the title transformations are generated in excellent yields with high enantioselectivities. Both processes can be performed within short reaction times and on gram scale. The similarity in results obtained in both reactions, combined with computational evidence, implies a common basis for stereoinduction and the possibility of a general catalytic mechanism for a-functionalizations. Promising initial results in alpha-amination and alpha-chlorination reactions support this hypothesis.

  has been developed for the synthesis of 2-arylacrylic esters from the corresponding aryl methyl ketones via Wittig reaction and singlet oxygen ene reaction. Wittig reaction to aryl methyl ketones with (methoxymethyl)triphenylphosphonium chloride in basic condition afforded the methyl enol ethers, and then 2-arylacrylic esters were obtained by singlet oxygen ene reaction, followed by tosylation and

  已经开发了一种有效的合成方法，用于通过Wittig反应和单线态氧烯反应从相应的芳基甲基酮合成2-芳基丙烯酸酯。在碱性条件下，与（甲氧基甲基）三苯基氯化在Wittig上与芳基甲基酮反应，得到甲基烯醇醚，然后通过单线态氧烯反应得到2-芳基丙烯酸酯，然后甲苯磺酸化并在一锅中消除为甲基烯醇醚。良品率高。
