Direct ring fluorination of 3-substituted 5-(1,3-dioxane) acetal isoxazoles: application to the formal synthesis of a bioactive fluorinated isoxazole

Comptes Rendus. Chimie
The access to a novel variety of 4-fluorinated isoxazoles bearing an aryl or alkyl group at the C-3 position and an acetal fragment at the C-5 position has been achieved through a direct fluorination using N-fluorobenzenesulfonimide (NFSI) with yields up

Studies with Arylhydrazono-3-oxopropanals:A novel route to synthesis of substituted pyrazoles, oxoalkanonitrile and glyoxalonitrile containing sulfa drug moieties [PDF]

, 2008
Coupling of enaminones 1 with diazonium salts gave thehydrazonopropanals 3a-h. Compound 3 react with ω-bromoacetophenone or α-chloroacetanilide to yield 5 and 8. These compounds were cyclized smoothly into 6 and 9 respectively.
