    • We found that although stable under basic conditions, 2a instantly epimerizes when treated with diluted hydrogen chloride acid. Even a trace amount of acid can cause this epimerization even at-80°C. Thus, all glasswares used for keeping this compound were all carefully deacidified by washing them first with an alkaline solution and then with water
