of diethyl allylmalonate (6b), sterically nucleophilic alkenes, Mn(OAc)3·2H2O and Cu(OAc)2·H2O gives methylenecyclopentanes 13 to 17 in 17–100% yield by an oxidative free-radical annulation. Similarly, oxidative annulation of diethyl crotylmalonate and ethyl benzylacetoacetate with an alkene gives vinylcyclopentane (30) and tetralin (35).

A three step synthesis of various thiobarbiturate derivatives 17–24 was established. The first step is mediated by Mn(OAc)3, in order to generate a carbon-carbon bond between a terminal alkene and malonate. Derivatives 1–8 were obtained in moderate to good yields under mild conditions. This key step allows synthesis of a wide variety of lipophilic thiobarbiturates, which could be tested for their anticonvulsive or anesthesic potential.
