A novel traceless route for the synthesis of optically active functionalized tetramic acids and 2-amino-4-pyrrolinones on solid support is described. p-Nitrophenyl carbonate linker on Wang resin is used to anchor l-α-Amino acids by their N-terminus thus leaving the carboxylic function free for further elaboration. High yields and ee, in combination with the versatility implied by the wide range of commercially available building blocks, are the major advantages of the proposed methodology.
描述了一种在固体载体上合成光学活性功能化特特拉姆酸和 2-氨基-4-吡咯啉酮的新无痕路线。 Wang 树脂上的对硝基苯碳酸酯连接体用于通过其 N 末端锚定 L-α-氨基酸,从而使羧基功能自由以供进一步阐述。高产率和高效率,再加上各种商用构建模块所暗示的多功能性,是所提出方法的主要优点。
