Phenylselenoetherification of Some Δ5-Alkenols in the Presence of Pyridine, Ag2O, and AgOAc as Additives

An improved procedure for intramolecular cyclization of some Δ 5-aikenols using PhSeX (X=Cl, Br) was developed. We found that cyclization can be facilitated in the presence of pyridine, Ag2O, and AgQAc as additives. Thus, a catalytic

Regioselectivity in Cyclofunctionalization of Olefinic Alcohols with Benzeneselenenyl Halides at Different Temperatures

The regioselectivity in cyclofunctionalization of some acyclic olefinic alcohols with benzeneselenenyl halides (PhSeCl and PhSeBr) at different temperatures (-78 deg C, 0 deg C and room temperature) is investigated.It has been found that Δ4- and Δ5-alkenols are converted into five- and/or six-membered cyclic phenyl selenoethers, the yield of which decreases with increasing temperature.PhSeCl has been found to be more efficient than PhSeBr in the cyclization reactions.
