The novel secondary Friedel-Crafts acylation products of the arenes, dimethyl resorcinol, m-xylene, m-methylanisole and m-chlorotoluene using dichloroacetylchloride and anhydrous AlCIs are described. The formation of the unexpected products has been shown to depend on the nucleophilicity of the aren
An efficient synthesis of indenoindene-fused a-methylene-c-butyrolactones was carried out via a tandem intra-and intermolecular Friedel-Crafts reaction from the spiro-lactone, which can be easily prepared from ninhydrin by indium-mediated Barbier reaction of cinnamyl bromide.
