functionalization and subsequent intramolecular ring-opening/cyclization of vinylene carbonate with 2-pyrrolyl/indolylanilines, which leads to oxazolidinones in moderate to good yields. In this transformation, vinylene carbonate only eliminates one oxygen atom rather than –CO3 or CO2. Furthermore, some control experiments are conducted to elucidate the reaction mechanism.
在此,我们开发了铑催化的 C-H 官能化和随后的碳酸亚乙烯酯与 2-吡咯基/吲哚苯胺的分子内开环/环化,从而以中等至良好的产率生成恶唑烷酮。在这种转变中,碳酸亚乙烯酯只消除了一个氧原子而不是-CO 3或CO 2。此外,还进行了一些对照实验以阐明反应机理。
