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.
Cs2CO3 or CaO as promoters of ethyl N-{[(4-methylphenyl)sulphonyl]oxy}carbamate in amination reactions
Barani, Marco,Fioravanti, Stefania,Pellacani, Lucio,Tardella, Paolo A.
, p. 11235 - 11238 (2007/10/02)
Replacing triethylamine by heterogeneous inorganic bases makes it possible to aminate benzene or other nitrene acceptors, using the title reagent, previously reported to be scarcely reactive. Products of C-H insertion and/or those coming from intermediate aziridines are also obtained.
The Regiochemistry of the Radical Addition of N-Chloroamides to Enol Ethers
Caron, Gilles,Lessard, Jean
, p. 8039 - 8058 (2007/10/02)
The orientation of the radical addition of N-chloroamides (ZCONHCl) to enol ethers was studied as a function of Z and the enol ether structure and compared with the orientation of radical addition of thioacetic acid and the orientation of typical electrop
A NOVEL SYNTHESIS OF N-SUBSTITUTED α-AMINO KETONES
Lociuro, Sergio,Pellacani, Lucio,Tardella, Paolo A.
, p. 593 - 596 (2007/10/02)
The thermolysis of ethyl azidoformate in enol trimethylsilyl ethers, followed by silica gel treatment, offers a new route to N-ethoxycarbonyl α-amino ketones.
