(−)-(3S)-3-(Tosylamino)butano-4-lactone (1) and its derivative ethyl (−)-(3S)-4-iodo-3-(tosylamino)butanoate (2) are presented as easily accessible chiral building blocks for the construction of a range of different macrolactam frameworks important for the synthesis of naturally occurring polyamine alkaloids as well as for establishing a substance library of such compounds, including S-containing derivatives
(-)-(3S)-3-(Tosylamino)butano-4-lactone (1) 及其衍生物 (-)-(3S)-4-iodo-3-(tosylamino)butanoate (2) 很容易呈现用于构建一系列不同的大环内酰胺骨架,这些骨架对于合成天然存在的多胺生物碱以及建立此类化合物的物质库很重要,包括用于生物测试的含硫衍生物。除此之外,根据新方法通过全合成确定了来自合欢的精胺生物碱 (-)-(R)-budmunchiamine A (3) 的绝对构型。
