abstract = "A stereoselective free radical introduction of a phenylthio group onto a nonactivated methyl group in the 8-position, adjacent to a prochiral carbon atom, was achieved by photolysis of (-)-menthyl benzenesulfenate in the presence of hexabutylditin and (1R, 3R, 4S, 8S)-9-phenylthiomenthot (4) was obtained with 91 % optical purity. High stereoselectivity of the reaction was calculated (ab initio MP2/6-3 1G**) to be the consequence of the difference in the transition state eneregies (DeltaDeltaG(#) = 5.08 kJ/mol) favouring 4 relative to (1R,3R,4S,8R)-9-phenylthiomenthoI (5). The absolute configuration of a the new chiral carbon atom was confirmed by its correlation with the corresponding menthane-3,9-diol of known stereochemistry., Fotolizom (–)-mentil-benzensulfenata u prisustvu heksabutil-dikalaja izvršeno je stereoselektivno uvođenje feniltio grupe na neaktiviranu metil grupu u δ-položaju koja je susedna prohiralnom ugljenikovom atomu i dobiven je (1R 3R, 4S, 8S)-9-feniltio-mentol (4) sa 91 % optičke čistoće. Visoka stereoselektivnost reakcije, potvrđena računom (ab initio MP2/6-21G**) posledica je razlike u energijama prelaznih stanja ΔΔG# = 5.08 kJ/mol) koja favorizuje nastajanje 4 u odnosu na (1R, 3R, 4S, 8R)-9-feniltio-mentol (5). Apsolutna konfiguracija novog hiralnog ugljenikovog atoma potvrđena je korelacijom s odgovarajućim mentan-3,9-diolom poznate stereohemije.",
