Synthesis of a series of novel fused pyrazolines and pyrazoles has been accomplished in good yields by regio- and diastereoselective 1,3-dipolar cycloaddition of enamines of indan-1-one 1a-c towards C-aryl-N-phenylnitrilimines 2d- f. The structure of

The reaction of the 2-benzoyl-1,2-dihydroisoquinaldonitrile fluoroborate salt with indene leads to a single indeno[1,2-c]pyrrole derivative. But nmr data did not prove the regiochemistry of the reaction and a chemical demonstration has been carried o

1,3-dipolar cycloaddition of (E)-arylidene-(2H)-indanones 1 (Ar = Ph, p-MeC6H4, p-MeOC6H4, p-ClC6H4) and (E)-2-arylidene-(2H)-tetralones 2 (Ar = Ph, p-MeC6H4, p-MeOC6H4, p-ClC6H4) to N-metalated azomethine ylides 3 generated from methyl N-arylidenegl

Étude de la stéréochimie de la réaction de cycloaddition dipolaire-1,3 de quelques 5-phényl-3,6-dihydro-2H-1,4-oxazin-2-ones avec les N-méthyl et N-phénylmaléimides

Six derivatives of 5-phenyl-3,4-dihydro-2H-1,4-oxazin-2-ones 1 were synthetized from α-amino acids. These compounds are precursors of six-membered cyclic azomethine ylids involving one stereocenter. The 1,3-dipolar species react with N-methyl and N-

The regio- and stereochemistry of spiro-adducts derived from [4+2] cycloaddition between the title compounds were deduced by 1H NMR data and the elucidated structure of the tetrasubstituted pyrroles obtained by acidic hydrolysis.

ChemInform Abstract: Reaction of 2-Benzoyl-1,2-dihydroisoquinaldonitrile Hydrofluoroborate Salt with Some 1,4-Quinones

Autor: N. Rodier, Bernard Laude, F. Theobald, Karin Monnier, Gérard Schmitt

Publikováno v: ChemInform. 23

In all reactions studied up to the present time with olefins, the Reissert hydrofluoroborate salts have given only the Diels-Alder adducts. With 1,4-benzo- and naphtoquinones, we have found evidence for 1,3-dipolar cycloaddition. The structure of cyc
