Magnesium-promoted one-pot double C-acylation and cycloaddition of anthracene and double C-acylation of benzyl acrylates

摘要

Treatment of anthracene or benzyl acrylate with magnesium turnings for Grignard reaction in the presence of various acid chlorides in N,N-dimethylformamide at room temperature brought about one-pot reductive double C-acylation or tandem intermolecular cycloaddition to give the corresponding C-diacylated products in satisfactory yields.
