AN EFFICIENT METHOD FOR HYDROLYSIS OF N-MONOSUBSTITUTED AMIDES VIA ACETOXYPIVALIMIDES
Tsunoda, Tetsuto,Sasaki, Osamu,Ito, Sho
, p. 731 - 734 (1990)
Various N-monosubstituted carboxamides were efficiently hydrolyzed in two steps through acetoxypivalimides.The method can be applied to a wide range of amides without racemization of α-position of the acyl groups.The amines can also be recovered.
