  摘要：

  重氮化合物的竞争性金属卡宾转化中，二铑 (II) 催化剂的羧酸盐和羧酰胺配体控制化学选择性。对于竞争性分子内环丙烷化与用 1-重氮-3-芳基-5-己烯-2-酮进行分子内芳烃取代，使用 Rh 2 (OAc) 4 会导致两种转化的产物几乎相等，但二铑 (II)全氟丁酸盐 (Rh 2 (pfb) 4 ) 仅提供芳族取代产物，而己内酰胺二铑 (II) (Rh 2 (cap) 4 ) 仅提供环丙烷化产物

  摘要：

  通过溴代烯丙烷的缩合，然后通过烷基卤化物与乙基丙二酸酯反应，我们制备了乙基烷基烯丙基丙二酸酯。这些酯的水解产生烷基-2Δ4-戊烯酸，利用双（3-甲基-2-丁基）硼烷，将其转化为烷基-2-羟基-5-戊酸。这些羟基酸的环化脱水反应产生烷基-3-δ-内酯。

  A diversity‐oriented approach to macrocycle libraries based on the “build/couple/pair” strategy was used to generate a virtual chemical space of 1.8 ⋅ 105 compounds, with a possibility to further expansion via the “post‐pairing” modifications. The method relied on a 4–5‐step reaction sequence including ring‐closing metathesis as the key step, with 61 % overall synthetic efficiency under parallel chemistry
