  Synthesis of α-methylenecyclopentanones via silicon directed nazarov reaction of α-trimethylsilymethyl substituted divinyl ketones.

  摘要：

  Reactions of alpha-trimethylsilylmethyl-substituted divinyl ketones with FeCl3 gave alpha-methylenecyclopentanones. Thienyl and N-methylpyrrolyl (alpha-trimethylsilylmethyl)vinyl ketones also underwent cyclization to afford the corresponding alpha-methylenecyclopentanones.

  The invention provides polymers of Formulas I-III, such as polyesters and unsaturated polyesters, and crosslinked and copolymerized polymers thereof. The invention also provides methods to catalytically ring-open five-membered rings such lactones, lactams, and thiolactones, as via ring-opening polymerization. The polymerization products are recyclable and can be depolymerized back to their monomer form via thermolysis and acid or base catalysis.
