the synthesis and ring-closing metathesis (RCM) of α,β-dehydroamino acids is described. This sequence has led to the formation of a range of biologically relevant functionalized nitrogen heterocycles. The incorporation of chiral building blocks in the RCM precursors eventually resulted in the formation of optically active 4-substituted cyclic dehydroamino acids. In addition, olefin isomerization under
描述了对α,β-脱氢氨基酸的合成和闭环复分解(RCM)的综合研究。该序列导致形成一系列生物学上相关的官能化氮杂环。在RCM前体中引入手性结构单元最终导致形成光学活性的4-取代的环状脱氢氨基酸。另外,在复分解条件下观察到许多化合物的烯烃异构化,通过引入烯丙基取代基或加入氢化钌清除剂可以成功地抑制烯烃异构化。
