M. Barani et al., IMPROVED AMINATION BY ETHYL N-([(4-NITROPHENYL)SULPHONYL]OXY) CARBAMATE IN THE PRESENCE OF INORGANIC OXIDES OR CARBONATES, Tetrahedron, 50(12), 1994, pp. 3829-3834
Inorganic solid bases give rise to alpha-elimination reactions of NsON
HCO2Et under easy and mild conditions without catalyst or ultrasounds.
For several kinds of substrates, a comparison of yields and reaction
times with previous methods is presented.
