Regioselective 1,3-dipolar cycloaddition reactions of 4-methylene-2- oxazolidinones with benzonitrile oxide

Substituted 4-methylene-2-oxazolidinones were prepared in two steps by cyclizing O-propargyl carbamates, which in turn were prepared from propargyl alcohols and phenyl isocyanate. The 4-methylene-2-oxazolidinones underwent a 1,3-dipolar cycloaddition reac

Reactions of 5-methylene-1,3-dioxolan-2-ones with amines. Synthesis of 2-oxazolidinones

The reaction of 5-methylene-1,3-dioxolan-2-ones with aromatic or aliphatic amines as well as with the sodium salts of amino acids leads to 4-hydroxy-2-oxazolidinones. The reaction conditions depend on the basicity of the amines. The use of o-phenylenediamine in this reaction leads to the formation of a new heterocyclic system. 1999 KluwerAcademic/Plenum.
