Abstract

NEW MATERIAL:The titled compound shown by the formula I [R<1> is lower alkyl or group shown by the formula II (n is 1-3), etc.; R<2> is H or a group shown by the formula -COOR<3> (R<3> is H or lower alkyl), etc. except that R<1> is lower alkyl having one phenyl with no substituent group] and its salt. EXAMPLE:alpha-Carboxy-delta-diphenylmethoxy-gamma-valerolactone. USE:A drug having antiallergic action, ulcer preventing action, anti-inflammatory action, inhibiting action of blood platelet aggregation, and depressant action of central nervous system. PROCESS:A compound shown by the formula III is reacted with a lower dialkyl malonate in the presence of a base (e.g., sodium hydride, sodium amide) in a solvent, e.g., benzene, at room temperature to the boiling point of the solvent for 1- several hours with stirring under heating, to give a compound shown by the formula I.
