Abstract: As an anti-allergic treatment for warm-blooded animals, therapeutic amounts of a compound having the formula I (including acid salts thereof) or II are administered: ##STR1## where; R is OR.sup.4 or NHR.sup.5 in which R.sup.4 is hydrogen or lower alkyl, R.sup.5 is selected from phenyl and phenyl monosubstituted with halogen, lower alkyl, lower alkoxy, R.sup.1 and R.sup.2 are independently hydrogen or lower alkyl, andR.sup.3 is selected from lower alkyl, arylcyclopropyl, naphthyl, phenyl, and phenyl monosubstituted with lower alkyl, lower alkoxy, trifluoromethyl, halogen, nitro, carboxyl, or ethyl carboxylate; ##STR2## R.sup.6 is lower alkyl, R.sup.7 is selected from phenyl and phenyl monosubstituted with lower alkyl, lower alkoxy, halogen or acetyl, and M is an alkali or alkaline earth metal.

Abstract: Alkali metal 2,5-dihydro-3-ethoxycarbonyl-2-[(substituted phenyl)amino]-4-furanyloxides are useful as anti-allergy agents.

Abstract: Compounds which possess antiallergy activity have the formula: ##STR1## wherein R is selected from phenyl and phenyl mono or disubstituted with lower alkyl, nitro, halogenated methyl, halogen, lower alkoxy and combinations thereof;wherein R.sup.1 is selected from hydrogen and lower alkyl; andwhere R.sup.2 is selected from phenyl, phenyl monosubstituted with lower alkyl, nitro, halogenated methyl, halogen, and lower alkoxy, and trans-phenylcyclopropyl in which the phenyl group may be substituted with lower alkyl or halogen.

Abstract: 4,5-dihydro-4-oxo-2-[(2-trans-phenylcyclopropyl)amino]-3-furancarboxylic acids and derivatives are described.

Abstract: Compounds useful as fragrance materials having the structure ##STR1## wherein each of R.sub.1, R.sub.2, and R.sub.3 are hydrogen or methyl can be prepared by reacting a halogen-containing cyclohexane, having the structure ##STR2## wherein each of R.sub.1, R.sub.2, and R.sub.3 are hydrogen or methyl and X is a halogen, with a reagent capable of effecting intramolecular cyclization.
