(Trialkylsilyl)manganese pentacarbonyl reagents react with epoxides and cyclic ethers in a regioselective manner to furnish functionalized alkylmanganese pentacarbonyl complexes.These complexes undergo subsequent sequential insertion with either alkenes or alkynes to afford manganacycles.Photodemetalation of the alkene-derived manganacycles give either aldol-like products or spiroketal lactone derivatives.Acid-catalyzed demetalation of alkyne adducts affords cyclopentenone derivatives by a Nazarov cyclization sequence.
