The present invention provides compounds of formula ##STR1## in which R represents an organic group, or a pharmaceutically acceptable metabolically labile ester or amide thereof, or a pharmaceutically acceptable salt thereof, which are useful as antagonists of one or more of the actions of L-glutamate at metabotropic excitatory amino acid receptors.
A new oxidativesubstitutionreaction where an organotin group is replaced by an acetoxy group has been investigated; this reaction has been successfully applied to the synthesis of 4-ylidenebutenolides.
