ENDO SELECTIVE CYCLIZATIONS OF SELENONIUM ION INTERMEDIATE - EFFICIENT FORMATION OF 1-HALO-3-SELENO-CYCLOHEXANES

Selenoacetal 1 was cyclized with tin(IV) chloride in the 6-Endo-Trig mode to give 1-chloro-3-methylselenocyclohexanes (2a,b) regio- and stereoselectively. Bromo- or iodocyclohexane derivatives were afforded by use of tin(IV) bromide or titanium(IV) iodide, respectively.
