The present invention provides a method of converting a hydroxy group in alcohols containing an electron withdrawing group into perfluoroalkane sulfonate and fluorosulfonate esters, which are good leaving groups, with inversion of configuration where the hydroxyl-bearing carbon is chiral. The method consists of converting an alcohol to an O—N,N-dialkylsulfamate ester and reacting it with a perfluoroalkansulfonic or fluorosulfonic acid. The method has applications in the synthesis of pharmaceutical and agrochemical compounds.
