摘要：

An addition of the Morita—Baylis—Hillman (MBH) carbonates to adamantane-containing isothiocyanates was studied. The MBH carbonates react with 1-(4-isothiocyanatophenyl)-adamantane in the presence of triphenylphosphine to give 5-aryl-substituted adamantane-containing 2-amino-4-methoxycarbonylthiophenes in 31–59% yields, while 1- and 2-isothio-cyanatoadamantanes were found unreactive in this reaction.
