Cathodically initiated Michael addition of thiols to levoglucosenone using small currents produces the previously unknown threo addition product in several instances. The normal erythro isomer, identified as the kinetic product, tends to be formed when large currents are used. The slow, low current electrolyses promote equilibration of the two forms so that erythro can be converted to threo by the
