摘要
采用DMSO-K2S2O8试剂体系,建立了一种直接将3- o -苄基化和硅基化甘醛转化为相应烯酮的简单、高效和区域选择性的方法。该反应在温和条件下可扩展到克数,收率可达80%。所得到的烯酮是合成呋喃[3,2-c]吡喃的有价值的中间体,呋喃是各种具有重要生物学意义的支架的组成部分。
DMSO–K2S2O8 mediated iodine-free conversion of glycal C-3 ether to 3-enopyranones: synthesis of furo[3,2-c] pyrans†
A straightforward, highly efficient, and regioselective method for directly converting 3-O-benzylated and silylated glycals into their corresponding enones has been developed using a DMSO–K2S2O8 reagent system. This reaction is scalable to gram quantities under mild conditions, achieving up to 80% yields. The resulting enones are valuable intermediates for the synthesis of furo[3,2-c] pyrans, which are integral components of various biologically significant scaffolds.
