The effects of the solvent and temperature on the reaction of the trans-glycidate (1) with various substituted thiophenols (2) in the presence or absence of a catalyst have been investigated.The temperature had a surprisingly large effect on the stereochemistry of the oxirane ring-opening of (1).At room temperature, the erythro-isomer (4) (trans-opening product) was obtained as a major product in the absence of catalyst, while the cis-opening product (3) (threo-isomer) was produced predominantly at higher temperature.On the other hand, in a dipolar aprotic solvent, the regioisomer (5) was formed, the yield increasing with the electron-donating ability of the substituents on (2).The formation of compound (5) may involve single-electron transfer as a key step.
