Δ4-Primary alkenols (Z)- and (E)-hex-4-en-l-ols underwent facile cyclization to the corresponding phenyl selenoethers using PhSeX (X = Cl, Br) in high yields and in good to excellent selectivities in the presence of some catalysts (Lewis acids

experimental part, p. 1373 - 1376 (2009/12/08)
A fast and efficient method for intramolecular heterocyclization of (Z)- and (E)-hex-4-en-1-ols was developed. The method does not cause side reactions of the substrates and provides the cyclic phenylselenoethers in high yields after only few minutes. A c

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.
