    • Chromone compounds having the structure ##SPC1##Wherein R is aryl, substituted aryl, thienyl, furyl or pyridyl, Y is hydroxy(lower)alkylene, R.sub.1 is hydrogen, lower alkyl, aryl, substituted aryl or a heterocyclic group, R.sub.2 is hydrogen or lower alkoxy, Y.sub.1 is lower alkylene or hydroxyl(lower)alkylene, Z is oxygen or sulfur and R.sub.3 is hydrogen, lower alkyl, aryl, substituted aryl, or ar(lower)alkyl have anti-allergic activity and are useful in the treatment of asthma. Compounds of the structure [I] are prepared by reacting ##SPC2##Wherein Y' is hydroxy(lower)alkylene whose hydroxy group is optimally protected or a reactive derivative of [II] with a carboxylic acid of the formula R--COOH in the presence of a basic catalyst. The resulting compound is then reacted with an acid. Compounds of the structure [I'] are prepared by reacting the compound ##SPC3##With the compound X--Y.sub.1 '--Z--R.sub.3 ' wherein X is an acid residue, Y' is lower alkylene or hydroxy(lower)alkylene whose hydroxy group is optionally protected by a protective group, R.sub.3 ' is hydrogen, lower alkyl, aryl, substituted aryl, or ar(lower)alkyl and Z is as defined above. When R.sub.3 ' is hydrogen, --Z--R.sub.3 ' is optionally protected by a protective group. The resultant compound is subjected to an elimination reaction when Y' is a protected group or when --Z--R.sub.3 ' is protected to split off the protective group.
