Iron halides are easily accessiable, cheap, and evrionmentally friendly reagents. Part I, the FeCl3∙6H2O catalyzed spiroannulation /1,5-hydride transfer of the alkynyl epoxides is described. Hydride transfer from the carbinol carbon to the newly formed cation center furnished α-hydroxyspiro[4.5]decaones in excellent stereoselectivity and good yields. Part II, the iron(II) chloride promoted cyclization reaction of cyclic-2-ynamides has been developed. The reactions were carried out under mild conditions and produced halogenated bicyclic [3.3.0] γ-lactams with four stereocenters with excellent stereoselectivity and in moderate yields. Part III, the iron (III) chloride promoted rearrangement/carbohalogenation of 3-(2-arylethynyl)-cyclohex- and panta-2-en-1-ynamines is described. This process involves a ketenimine rearrangement/carbochlorination affording bicyclo[3.2.1]oct-6-en-6-amines and [2.2.1]hept-2-en-2-amines in good to excellentyields with complete stereoselectivity. The reaction path was suggested confirmed by a double crossed experiment. The futher application of this ketenimine rearrangement is under current investigation.螺旋化合物15-氫負離子轉移氯化鐵炔醯炔胺化合物重排反應雙環[3.2.1]衍生物雙環 [2.2.1]衍生物內醯胺化反應鹵化反應氯化反應spiro compoundslactamizationiron chloride15-hydride transferrearrangementbicycle [3.2.1]/[2.2.1] derivativeschlorinationynamide
