On October 5, 2018, Wang, Mengdan; Kong, Lingkai; Wang, Ye; Song, Bo; Sun, Yue; Tang, Rong; Li, Yanzhong published an article.Application In Synthesis of 3-Acetyldihydrofuran-2(3H)-one The title of the article was Sequential C-C σ-Bond Cleavage/(sp2) C-O Bond Formation via C-H Functionalization toward Pyranoindolones Fused with Medium-Sized Rings. And the article contained the following:
An atom-economical procedure for the synthesis of pyranoindolones fused with 7- or 8-membered rings has been developed. This process is realized through the sequential Cs2CO3-promoted C-C σ-bond cleavage of cyclic ketoesters and a ZnI2-mediated selective C-H/O-H coupling reaction. Two of the C-C σ-bonds are cleaved and one of the sp2 C-H bonds is functionalized during the reaction process. Easily accessible starting materials and broad substrate scope make this protocol attractive in synthetic organic chem. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).Application In Synthesis of 3-Acetyldihydrofuran-2(3H)-one
