Acid treatment of the resultant chlorinated arylideneazabicyclooctanes furnished 3-alkanoyl-4-chlorocyclohex anamines in excellent yields and high stereoselectivity. （2） The iron(III) bromide-promoted cyclization of six-membered ring 1-yneynamides provided brominated spiro[3.5]nonane derivatives. The reaction mechanism was suggested to proceed via rearrangement of N-keteniminium ion to C-ketenimine followed by cyclization of C-ketenimine generated spiro[3.5]nonane derivatives. The reaction had several advantages: easily available starting materials, inexpensive iron (III) bromide, and short reaction times. （3） The gold (I)-catalyzed intramolecular cyclization of 1-[2-(N-tosyl-N-phenylethynylethyl)]cyclohexene afforded isoquinoline derivatives in fair good yields. The reactions were procedurally simple, efficient, producing isoquinolines under mild reaction conditions.
