HOTf-Catalyzed Rearrangement of Methylenecyclopropane Aryl and Alkyl Alcohols

[摘要]：An efficient method to synthesize multisubstituted naphthalene and cyclobutanol derivatives through ring opening/ring enlargement of readily available methylenecyclopropane diaryl alcohols or dialkyl- and monoalkyl- as well as monoaryl alcohols in moderate to good yields has been described in this paper. The formation of naphthalene derivatives is a sequential reaction involving a cation-induced ring opening of cyclopropane, a Friedel Crafts alkylation reaction, followed by aromatization. On the other hand, the production of cyclobutanol derivatives is a cation-induced ring-enlargement process. The scope and limitations have also been presented.
