Title: BIS-CHROMONE COMPOUNDS
Abstract:Compounds of the formula ##SPC1## Wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are each selected from hydrogen, halogen, hydroxy, lower alkyl, lower alkoxy, hydroxy lower alkyl, halo lower alkyl, hydroxy lower alkoxy and lower alkoxy lower alkoxy, X is selected from straight and branched, saturated and unsaturated hydrocarbon chains which are uninterrupted or interrupted by a member from the group of benzene, oxygen, and carbonyl and are unsubstituted or substituted by a member of the group of halogen, hydroxy and lower alkoxy, and YZ and Y'Z' are selected from ##SPC2## Wherein W represents carboxylic acid or functional derivatives or groups convertible thereto, with the proviso that YZ and Y'Z' are not both simultaneously the chain ##SPC3## The compounds are intermediates in the production of compounds useful as inhibitors of certain antigen-antibody reactions.
