Thus, we selected tBuOCl (2 equiv) with NaBr(1.5 equiv) under a balloon of CO2 in DMF and at −40°C as the reaction conditions. Notably, when using iodide as the nucleophile, no desired syn-1,3-diol was produced, suggesting that iodide was not suitable for this reaction. With the...
was added over a period of 15 min to DBU (1 equiv.) at 5 °C in an ice bath under ultrasound. The reaction mixture was irradiated under ultrasound for an additional period of 15 min at ambient temperature. Thus obtained oily residue was dried in vacuo at 60 °C for 1 h to afford ...
