Abstract:Thiolysis of a variety of 1,2-epoxides in water at
30 °C and pH 7.0 is strongly accelerated by ZnCl2 (10 mol
%) except when amino- and carboxythiophenol are used.The
aqueous medium and the catalyst were recovered and reused
in various runs without affecting the efficiency of the process.
Introduction
The â-hydroxysulfide unit is present in compounds of
biological and pharmacological interest1 and is a versatile
moiety for synthesizing allylic alcohols,benzoxathiepines,
benzotiazepines,R-thioketones,R-substituted
R,â-unsaturated enones,and â-hydroxysulfoxides used
in the synthesis of naturally occurring compounds.
The easiest access to â-hydroxysulfides is the thiolysis
of 1,2-epoxides that is usually carried out in organic
solvents (THF,CH2Cl2,MeOH,MeCN,or PhH) by using
thiols under basic conditions8 or in the presence of
promotors and/or catalysts
