The generation of (Samarium) thiolates from aryl thiocyanates and their reaction with epoxides: A route to β-hydroxy sulfides
Still, Ian W.J.,Martyn, L. James P.
, p. 913 - 923 (1998)
This investigation describes the reduction of an aryl thiocyanate with samarium(II) iodide, followed by reaction with various epoxides, to produce β-hydroxy sulfides. This method of ring opening of epoxides provides a substantial improvement in reaction time and convenience over existing methods while maintaining good regioselectivity and excellent yield.

An efficient and rapid procedure for ring opening reaction of various epoxides with phenol and thiophenol derivatives was developed. The procedure can be obtained at room temperature under solvent-free condition in presence of (C4H12N2)2[BiCl6] Cl·H2O (1 mol %). This catalyst can be reused several times without significant loss of activity.

An efficient and rapid procedure is developed for room-temperature ring opening of various epoxides with thiols under solvent-free conditions in the presence of catalytic amount of superparamagnetic Fe3O4 nanoparticles. As a result,
The first example of amine-induced reversal of diastereoselectivity in acylation of some trans-2-substituted cyclohexanols
Samoshin, Andrey V.,Visser, Jasper,Curtis, Matthew,Samoshin, Vyacheslav V.,Franz, Andreas H.
experimental part, p. 27 - 35 (2012/08/14)
The reaction between racemic acyl chlorides and racemic trans-2-substituted-cyclohexanols proceeds diastereoselectively. We found for the first time that addition of a tertiary amine not only accelerates the acylation, but for some substituents leads to c

experimental part, p. 2113 - 2121 (2010/08/13)
Regio-, stereo-, and chemoselective ring opening of epoxides with thiols using Cu/MgO as a heterogeneous catalyst has efficiently been carried out to produce the corresponding β-hydroxy sulfides in excellent yields at room temperature under solvent-free c

Kawamata, Yoshiyuki,Oriyama, Takeshi
experimental part, p. 382 - 384 (2010/07/06)
Kinetic resolution of cyclic β-hydroxy sulfides has been achieved by reaction with benzoyl chloride in the presence of a catalytic amount (0.1 mol %) of a chiral 1,2-diamine combined with triethylamine. This reaction affords the corresponding benzoates and unreacted alcohols with excellent enantioselectivities.

A chiral heterobimetallic Lewis acid complex has been developed as an efficient catalyst. The enantioselective desymmetrization of meso-epoxides with aryl selenols and thiols catalyzed by the heterobimetallic complex has been optimized. The optically active β-arylseleno alcohols and β-hydroxy sulfides were obtained in good yields and high enantioselec- tivities (up to 97% ee and 92% ee, respectively). A strong synergistic effect between different Lewis acids was exhibited in the catalytic process. & copy; 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
