An improved procedure for intramolecular cyclization of some Delta(5)-alkenols using PhSex (X = Cl, Br) was developed. We found that cyclization can be facilitated in the presence of pyridine, Ag2O, and AgOAc as additives. Thus, a catalytic amount of additive influenced higher yields and equimolar amounts achieved almost quantitative yields under extremely mild experimental conditions. The effect of the halide ion of the selenylating reagent was not significant.
