Article abstract of DOI:10.1016/S0040-4039(00)71230-5

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.
