synthetic studies of nemorosone via enantioselective intramolecular cyclopropanation. For the total synthesis of nemorosone, three potential intermediates were evaluated through the efficiency of three sequential reactions, namely, their intramolecular cyclopropanation, dimethylation of the resultant cyclopropanes, and ring-opening reaction of the alkylated cyclopropanes. As a result, α-diazomethyl ketone
