Compositions for the oxidative dyeing of keratin fibers, comprising a medium suitable for dyeing and at least one bicyclic 6-6 (0:1, 0:2, 1:1, 1:2) aza heteroaromatic keratin dyeing compound with one or two N-oxides. A method for oxidative dyeing of kerat

Synthesis of 3-methoxyquinolines via cyclization of 1-isocyano-2-(2-lithio-2-methoxyethenyl)benzenes

2-(2-Isocyanophenyl)acetaldehyde dimethyl acetals were treated with excess LDA to generate 1-isocyano-2-(2-lithio-2-methoxyethenyl)benzenes, which cyclized intramolecularly to afford 3-methoxyquinolines in good to excellent yields.

Palladium-Catalyzed Synthesis of Indoles from 2-Nitrostyrenes

In the presence of palladium salts, oxidation of 2-nitrostyrenes 1 with nitrous acid alkyl esters 2 resulted in the formation of 2-nitrophenylacetaldehyde dialkyl acetals 3.Reductive cyclization of the acetals 3 with iron powder in acetic acid afforded indoles 5 in good yield.
