Amination of Optically Active Azaallylic Anions
Fioravanti, Stefania,Olivieri, Lauso,Pellacani, Lucio,Tardella, Paolo A.
, p. 338 - 339 (2007/10/03)
The reaction of azaallylic anions with ethyl N-[4-nitrobenzenesulfonyl)oxy]carbamate in the presence of a base gives a mixture of an α-amino ketone derivative with a slight preference for the (S) enantiomer and of an α-hydrazino ketone derivative as by-product; the same azaenolates react with bis(tert-butoxycarbonyl)diazene giving the analogous α-hydrazino ketone derivative, with a slight preference for the (R) enantiomer.
Improved amination by ethyl n-(4-nitrophenyl)sulphonyloxy carbamate in the presence of inorganic oxides or carbonates
Barani, Marco,Fioravanti, Stefania,Antonietta Loreto,Pellacani, Lucio,Tardella, Paolo A.
, p. 3829 - 3834 (2007/10/02)
Inorganic solid bases give rise to α-elimination reactions of NsONHCO2Et 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.
