Synthesis of sterically hindered N-acylated amino acids from N-carboxyanhydrides
Schaefer, Gabriel,Bode, Jeffrey W.
supporting information, p. 1526 - 1529 (2014/04/03)
Sterically hindered N-acyl, gem-disubstituted amino acids are easily prepared via the addition of organometallic reagents to N-carboxyanhydrides (NCA). The process tolerates a wide variety of functional groups and allows the synthesis of amide products not readily accessible by traditional acylation chemistry. The existence of an isocyanate intermediate was established by in situ IR spectroscopy.

A method of synthesizing an optically active cyclic methionine analogue, 3-aminotetrahydrothiophene-3-carboxylic acid (At5c), is described. A Bucherer-Bergs reaction of 4,5-dihydro-3(2H)-thiophenone and the subsequent alkaline hydrolysis of a h
A new series of cyclic amino acids as inhibitors of S-adenosyl L- methionine synthetase

Optically active 3-amino-3-(tetrahydrofuranyl) carboxylic acid, 3- amino-3-(tetrahydrothienyl) carboxylic acid and their corresponding six membered ring analogues have been synthesised and examined as potential inhibitors of the enzyme S-adenosylmethionine (AdoMet) synthetase. The kinetic behaviour of these compounds was studied using recombinant rat liver AdoMet synthetase (α-isoform) fractionated from E. coli transformed with the plasmid pSSRL-T7N. All the compounds tested were competitive inhibitors of the enzyme with respect to L-methionine.
