their increasing utility, their preparation typically requires multiple steps in low overall yield. In this work, we report an expedient and general one-pot procedure for the synthesis of 1-sulfonylbicyclo[1.1.0]butanes from readily available methyl sulfones and inexpensive epichlorohydrin via the dialkylmagnesium-mediated formation of 3-sulfonylcyclobutanol intermediates. Furthermore, the process was

The scalablesynthesis of the oxaquinolizidine marine natural product desmethylxestosponginB is based on the early application of Ireland–Claisen rearrangement, macrolactamization, and a late‐stage installation of the oxaquinolizidine units by lactam reduction. The synthesis serves as the source of material to investigate calcium signaling and its effect on mitochondrial metabolism in various cell
oxaquinolizidine 海洋天然产物 desmethylxestospongin B 的可扩展合成是基于 Ireland-Claisen 重排、大环内酰胺化和通过内酰胺还原后期安装 oxaquinolizidine 单元的早期应用。该合成可作为研究钙信号传导及其对包括癌细胞在内的各种细胞类型中线粒体代谢的影响的材料来源。
