advance transition-metal-catalyzed cycloadditions for the synthesis of various-sized ring compounds. A new seven-carbon building block from buta-1,3-dienylcyclopropanes (BDCPs) has been developed, showing that, under the catalysis of [Rh(CO)2Cl]2, BDCPs react with CO to give [7 + 1] cycloaddition products, cyclooctadienones. The present [7 + 1] reaction provides an efficient entry to the synthetically
A Fe2(CO)9-mediated [5+1] cycloaddition of vinylcyclopropanes (VCPs) and CO to α, β-cyclohexenones has been developed. The reaction can tolerate aryl and aliphatic groups at the α-position of VCPs, while VCP substrates with vinyl or alkynyl substitutions are not suitable ones. In addition, this reaction can also be used to synthesize bicyclic rings if an aryl group is attached to the vinyl moiety of

of rhodium: Highly functionalized seven‐membered rings were prepared from substitutedcyclopropanes by a RhI‐catalyzed tandem isomerization reaction. The π‐acidic RhI catalyst promoted the formation of an allene intermediate by a 1,3 acyloxy migration of a propargyl ester and a subsequent net 1,5 migration of a cyclopropane CC bond.
