An efficient total synthesis of antibiotic (−)-codonopsinine 1 with an overall yield of 44% was achieved from d-alanine as a chiral template. The key steps in our strategy are modified Sharpless asymmetric dihydroxylation reaction and the highly stereoselective intramolecular acid-catalyzed amidocyclization.
以d-丙氨酸为手性模板,可以有效地合成抗生素(-)-codonopsinine 1,总产率为44%。我们策略中的关键步骤是修饰的Sharpless不对称二羟基化反应和高度立体选择性分子内酸催化的酰胺基环化反应。
