Titanocene(III) chloride (Cp2TiCl) mediated one-pot synthesis of furan derivatives has been accomplished. This radical method has been applied for the synthesis of a furanomonoterpene, evodone. Ti(III) species was prepared in situ from commercially available titanocene dichloride (Cp2TiCl2) and zinc dust in THF.
