Conversion of a hydroxy group in certain alcohols into a fluorosulfonate ester or a trifluoromethylsulfonate ester |
| abstract |
The present invention provides a method of converting a hydroxy group in alcohols containing an electron withdrawing group into perfluoroalkanesulphonate and fluorosulphonate esters, which are good leaving groups, with inversion of configuration where the hydroxyl-bearing carbon is chiral. The method consists of converting said alcohol to an O-N,N-dialkylsulphamate ester and reacting said O-N,N-dialkylsulphamate ester with a perfluoroalkanesulphonic acid or fluorosulphonic acid. Such a method is useful for preparing chiral compounds for pharmaceutical and agrochemical use. |
