Asymmetric Synthesis of Diastereomeric Diaminoheptanetetraols. A Proposal for the Configuration of (+)-Zwittermicin A
摘要:
A proposed absolute configuration for the 7 stereocenters in (+)-zwittermicin A is described based on asymmetric synthesis of six diastereomeric 2,6-diamino-1,3,5,7-heptanetetraols corresponding to the C9-C15 segment, pairwise C-13 NMR chemical shift difference analysis of the models with the natural product, interpretation of enantiospecificity of the serine loading domain of the zwittermicin A biosynthetic gene cluster, and degradation of the natural product.
