Methyl arylchloropyruvates undergo intermolecular self-condensation in the presence of a catalytic amount of a base under high-temperature conditions (~250°C) with the formation of 3,4-diaryl-2-oxo-2,3-dihydrofuran-3,5-dicarboxylic acid derivatives.

Regioselective ring opening of 3-aryl-2-cyano-2-(methoxycarbonyl)oxiranes 1 with transition metal halides (copper(II) chloride, copper (II) bromide, zinc bromide, cobalt chloride and ferric chloride) and silica-gel-supported metal halides gave methyl 3-aryl-2-cyano-3-halo-2-hydroxypropanoates 5, 6 and methyl 3-aryl-3-halo-2-oxopropanoates 2, 3.The reaction of 1 in chlorobenzene under reflux with silica-gel-supported copper (II) halides gave but-3-en-4-olides 4.Key Words: methyl 3-aryl-2-cyano-3-halo-2-hydroxypropanoates; methyl 3-aryl-3-halo-2-oxopropanoates; but-3-en-4-olides.
