Studies on the Asymmetric Synthesis of cis-5-Alkyl-4-hydroxy-2–pyrrolidinones and Studies on the New Method for Reduction of Amide [PDF]

open access: yes, 2009
本论文包含以下各自独立的三方面内容:1,顺式-4-羟基-5-烷基-2-吡咯烷酮4的不对称合成研究;2,CytosporoneB类单羟基衍生物的合成;3,酰胺还原新方法研究。 一、顺式-4-羟基-5-烷基-2-吡咯烷酮4的不对称合成研究: 很多天然产物中含有顺式-4-羟基-5-烷基-2-吡咯烷酮亚结构,它们大多数具有很好的生理活性。此结构开环后得到的γ-氨基-β-羟基酸是一类特种氨基酸,它们是许多具有重要生理活性天然产物的结构单元。因此,关于此类化合物的研究一直吸引着人们的兴趣 ...
