Albanese, Domenico,Landini, Dario,Lupi, Vittoria,Penso, Michele
, p. 1443 - 1449 (2000)
N-(2-Nitrophenylsulfonyl)- (o-NBS-AA-OMe, 4) and N-(4- Nitrophenylsulfonyl)-α-amino acid methyl esters (p-NBSAA-OMe, 5) were N- alkylated with a variety of alkyl halides 6 under solid-liquid phase-transfer catalysis (SL-PTC) conditions, affording the alkylated products o-NBS-N-R2- AA-OMe 7 and p-NBS-N-R2-AA-OMe 8 in excellent yields without any detectable racemization.
Enantioselective amination of silylketene acetals with (N-arylsulfonylimino)phenyliodinanes catalyzed by chiral dirhodium(II) carboxylates: asymmetric synthesis of phenylglycine derivatives

The first catalytic enantioselective amination of silylketene acetals with (N-arylsulfonylimino)phenyliodinanes is described. The reaction of silylketene acetals derived from methyl phenylacetates with [N-(2-nitrophenylsulfonyl)imino]phenyliodinane (NsN =
Convenient synthesis of N-methylamino acids compatible with Fmoc solid-phase peptide synthesis
Biron, Eric,Kessler, Horst
, p. 5183 - 5189 (2007/10/03)
Nα-Methylamino acid containing peptides exhibit interesting therapeutic profiles and are increasingly recognized as potentially useful therapeutics. Unfortunately, their synthesis is hampered by the high price and unavaibility of many Nα/
