A new and efficient protocol to prepare indenes is reported. Assisted by boron trifluoride diethyl etherate, the one-pot reaction of aryl homopropargyl alcohols and aldehydes in the presence of arenes yielded indene derivatives. The reaction was studied with various substrates, which suggests a cascade reaction including a sequence of Prins, Friedel-Crafts, ring-opening reactions, and Friedel-Crafts to form three C-C bonds leading to indenes.
Synthesis of the indene, THF, and pyrrolidine skeletons by lewis acid mediated cycloaddition of methylenecyclopropanes with aldehydes, N-tosyl aldimines, and acetals

Methylenecyclopropanes (MCPs 1) react with aldehydes, N-tosyl aldimines, and acetals to give the corresponding indene. THE and pyrrolidine cyclo-addition products in the presence of BF2·'OEt2 under mild reaction conditions. Some special transformations of MCPs 1 with aldehydes have been reported in this paper. A plausible reaction mechanism has been discussed, which is based on a deuterium-labeling experiment and the Prins-type reaction mechanism.
Lewis acid-mediated cycloaddition of methylenecyclopropanes with aldehydes and imines: A facile access to indene, THF, and pyrrolidine Skeletons via Homoallylic Rearrangement Protocol

Methylenecyclopropanes (MCPs) 1 can react with aldehydes and aldimines to give the corresponding indene, THF, and pyrrolidine cycloaddition products in the presence of BF3·OEt2 under mild reaction conditions.
