A preparatively simple diastereoselective synthesis of the amino acid chimera (1S,3S)-1,2,3,4-tetrahydroisoquinoline-1,3-dicarboxylic acid from hexafluoroacetone-protected phenylalanine and glyoxylic acid hydrate via Pictet-Spengler reaction is described. The potential of the reaction of hexafluoroacetone-protected phenylalanine with other aldehydes was scrutinized.
本文报道了一种预处理简单的非对映选择性合成氨基酸嵌合体(1S,3S)-1,2,3,4-四氢异喹啉-1,3-二羧酸的方法,该方法通过Pictet-Spengler反应,以六氟丙酮保护的苯丙氨酸和甘油酸水合物为原料。同时,探讨了六氟丙酮保护的苯丙氨酸与其他醛类反应的潜力。
