METHOD OF IMPROVING STABILITY OF SWEET ENHANCER AND COMPOSITION CONTAINING STABILIZED SWEET ENHANCER

The present invention includes methods of stabilizing one or more sweet enhancers when they are exposed to a light source as well as liquid compositions containing one or more sweet enhancers and one or more photostabilizers.

Heterocycle-to-heterocycle route to quinoline-4-amines: Reductive heterocyclization of 3-(2-nitrophenyl)isoxazoles

A variety of quinoline-4-amines were synthesized from substituted 3-(2-nitrophenyl)isoxazoles utilizing Zn0 or Fe0 dust and HOAc using a reductive heterocyclization process. The starting isoxazoles were synthesized from readily available starting materials. A brief survey of functional groups tolerated in this reductive heterocyclization was performed and several 10-amino-3,4-dihydrobenzo[b][1,6]naphthyridin-1(2H)-one and 9-amino-3,4-dihydroacridin-1(2H)-one examples were synthesized.

Synthesis of 4-Quinolone Derivatives

Routes to 4-amino-2-alkyl substituted quinoline-3-carboxylic acids and 3-acyl-2-phenyl and 3-acyl-2-alkyl substituted 4-quinolones have been devised by application of isoxazole chemistry and Heck-Stille couplings.

Sur les orthoamino formyl quinoleines, nouveaux synthons heterocycliques

Les quatre orthoamino formyl quinoleines substituees sur le cycle pyridinique ont ete synthetisees par oxydation des amino hydroxymethyl quinoleines correspondantes.Parmi toutes les methodes envisagees, seule cette derniere a permis la preparation de l'amino-3 formyl-2 quinoleine, compose relativement peu stable.Ces nouveaux composes bifonctionnels derives de la qunoleine constituent des synthons particulierement interessants pour l'elaboration de certains heterocycles.
