Copper-mediated tandem ring-opening/cyclization reactions of cyclopropanols with aryldiazonium salts: Synthesis of: N -arylpyrazoles

A general method for the synthesis of structurally diverse N-arylpyrazoles from readily available cyclopropanols and aryldiazonium salts is disclosed. The reaction was conducted at room temperature within minutes with a broad substrate scope and excellent regioselectivity.

Thermolysis of Polyazapentadienes. Part 7. An Unambiguous Route to 7-Substituted Quinolines from Cinnamaldehyde Derivatives

Flash vacuum pyrolysis of the cinnamaldehyde phenylhydrazone derivatives (4) - (6) or O-alkyl oxime derivatives (7) - (12) at 600 -650 deg C and 10-2 - 10-3 Torr leads to approximately equal quantities of cinnamonitriles and quinolines.Use of a p-substituted cinnamaldehyde derivatives gives the appropriate 7-substituted quinoline in high isomeric purity; the reactions take place via conjugated iminyl radicals.
