| titleOfInvention | Oxaloamino substituted fluorinated resorcinol ethers and anti-allergic and anti-inflammatory use thereof |
| abstract | 4-Acylresorcinol esthers of the formula <IMAGE> (I) in which R1 is lower alkyl, R2 is fluorinated lower alkyl, R3 is hydrogen, lower alkoxy, trifluoromethyl or halogen, alk is an alkylene or hydroxyalkylene radical which is uninterrupted or interrupted by oxygen, one of the radicals R4, R5 and R7 is a group of the formula -NH-C(=O)-R8, a radical R4 or R5 which differs from this is a radical R9 and a radical R7 which differs from this is a radical R10, R6 is hydrogen, lower alkyl, trifluoromethyl, halogen, carboxyl which is free, esterified or amidated, cyano or lower alkanoyl, R8 is carboxyl which is free, esterified or amidated or 5-tetrazolyl, R9 is hydrogen, lower alkyl, lower alkoxy, halogen or trifluoromethyl and R10 is hydrogen, lower alkyl, lower alkoxy, halogen, trifluoromethyl, cyano or carboxyl which is free, esterified or amidated, and their salts have antiallergic and antiinflammatory properties. They are prepared, for example, by reacting compounds of the formulae <IMAGE> in which one of the radicals X5 and X6 is hydroxyl which is free or in salt form and the other is an alkoxy radical substituted by reactive esterified hydroxy or epoxy. The invention also relates to intermediates of the formula <IMAGE> (XXXIII) in which R2 is fluorinated lower alkyl, R3 is hydrogen, lower alkoxy, trifluoromethyl or halogen and R11 is hydrogen or a group of the formula R1-C(-O)-, in which R1 is lower alkyl, and their salts. |
