One-pot three-component synthesis, structure and redox properties of ferrocenyl isoxazoles

Willy, Benjamin,Frank, Walter,Rominger, Frank,Müller, Thomas J.J.

, p. 942 - 949 (2009/05/27)

A consecutive coupling-cycloaddition sequence of acid chlorides, terminal alkynes, and in situ generated nitrile oxides furnishes ferrocenyl substituted redox active isoxazoles in moderate to good yields. The structure was unambiguously assigned by X-ray
