Reaction information

*#Reaction file
*Reaction file type CDX
*Procedure Following the procedure reported by Whistler, the bis-tosylate, trans-O,O’-Cyclohexane-1,4-diylbis(methylene)toluensulfonate (905 mg, 2.00 mmol) and potassium thiolacetate (594 mg, 5.20 mmol, 2.60 eq) were reacted in 4 mL of acetone. Work-up and evaporation of the solvent yielded the crude product (brownish solid, 485 mg, purity 95% including the cis-contaminant, reaction yield 79%); this was dissolved in Et2O and treated with decolourizing charcoal. The yellow solid obtained (396 mg) was recrystallized twice in cold EtOH/H2O (flakes) to yield the pure product (white waxy solid, 52 mg, 0.20 mmol, yield 10%; purity > 95% trans-isomer). Rf 0.69 (UV 254 nm; 4/1 Et20/hexane).
*Yield (%) 10 %
*Type of Yield Isolated pure product
