Biodegradable choline hydroxide promoted environmentally benign thiolysis of epoxides
Azizi, Najmedin,Edrisi, Mahtab
supporting information, p. 525 - 528 (2016/01/20)
An environmentally benign and rapid thiolysis of epoxides using a biodegradable, choline-based task-specific ionic liquid has been developed. The ring opening reaction of aryl and alkyl epoxides proceeded rapidly and afforded the corresponding β-hydroxysulfides in high yields with excellent regioselectivity. The protocol has the advantages of easy work-up, short reaction times, high yields, and a biodegradable catalyst.
Rapid, benign, and additive-free thiolysis of epoxides under ultrasonic/aqueous conditions
Mojtahedi, Mohammad M.,Khalili, Sajad
, p. 431 - 437 (2014/06/10)
An environmentally friendly and efficient procedure is developed for ring opening of various epoxides with thiols under non-thermal conditions. Reactions take place by ultrasonic irradiation of the two reactants suspended in an additive-free aqueous mediu

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
Catalytic asymmetric ring-opening reaction of meso-epoxides with aryl selenols and thiols catalyzed by a heterobimetallic gallium-titanium-salen complex
Sun, Jiangtao,Yang, Minghua,Yuan, Fang,Jia, Xuefeng,Yang, Xia,Pan, Yi,Zhu, Chengjian
supporting information; experimental part, p. 920 - 930 (2009/11/30)
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.
