Mojsilovic, Biljana M.,Bugarcic, Zorica M.
, p. 475 - 479 (2001)
An improved procedure for intramolecular cyclization of tertiary alkenols using benzeneselenyl halides has been developed. We found that cyclization can be facilitated by pyridine. Thus, in the presence of an equimolar amount of pyridine, a chemospecific

Bugarcic, Zorica M.,Divac, Vera M.,Gavrilovic, Mariana P.
, p. 985 - 988 (2008/03/17)
An efficient protocol for the preparation of phenylselenoethers from unsaturated alcohols using phenylselenenyl halides at room temperature was developed. The procedure employs phenylselenenyl chloride and bromide, some Δ 4- and Δ 5-

An improved procedure for intramolecular cyclization of some Δ5-alkenols, using PhSeX (X = Cl, Br) has been developed. We found that cyclization can be facilitated in the presence of pyridine, Ag 2O, and some Lewis acids as catalysts

, p. 1359 - 1363 (2007/10/03)
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

, p. 261 - 268 (2007/10/02)
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.

Electrochemical cyclization of unsaturated hydroxy compounds. Phenylselenoetherification and phenylselenolactonization
Vukicevic,Konstantinovic,Mihailovic
, p. 859 - 865 (2007/10/02)
Phenylselenoetherification and phenylselenolactonization were performed in one step by electrolysis of unsaturated alcohols or carboxylic acids and diphenyl diselenide in organic solvent containing halide ions as mediators.
ELECTROCHEMICAL CYCLIZATION OF UNSATURATED HYDROXY COMPOUNDS. PART I. PHENYLSELENOETHERIFICATION
Mihailovic, M. Lj.,Konstantinovic, S.,Vukicevic, R.
, p. 4343 - 4346 (2007/10/02)
One-step cyclization of alkenols has been accomplished by electrooxidative phenylselenoetherification.The reaction was performed by electrolysis of unsaturated alcohols and diphenyl diselenide in methylene chloride containing tetraethylammonium bromide.
