Synthesis of optically active (R)- And (S)-β-arginine from pyroglutamic acid
Yasuno, Yoko,Sawai, Akira,Sekihara, Ai,Shinada, Tetsuro
, p. 165 - 176 (2020/02/04)
– The first synthesis of optically active β-arginine was achieved starting from commercially available pyroglutamic acid. The new synthetic protocol is characterized by the use of nitrile as a carboxylic acid surrogate which could be transformed to the co

Total synthesis of (-)-martinellic acid
Badarinarayana, Vivek,Lovely, Carl J.
, p. 2607 - 2610 (2007/10/03)
An enantioselective formal total synthesis of the pyrrolo[3,2-c]quinoline natural product martinellic acid has been achieved. The key steps involve a Pd-catalyzed aryl amidation reaction of a pyrroglutamate derivative, an intramolecular [3+2] azomethine ylide-alkene cycloaddition and a reductive ring opening reaction.
Total synthesis of (+)-batzelladine A and (-)-batzelladine D via [4 + 2]-annulation of vinyl carbodiimides with N-alkyl imines
Arnold, Michael A.,Day, Kenneth A.,Duron, Sergio G.,Gin, David Y.
, p. 13255 - 13260 (2008/03/11)
A diastereoselective [4 + 2]-annulation of vinyl carbodiimides with chiral N-alkyl imines has been developed to access the stereochemically rich polycyclic guanidine cores of the batzelladine alkaloids. Application of this strategy, together with additional key steps such as long-range directed hydrogenation and diastereoselective intramolecular iodo-amination, led to highly convergent total syntheses of (-)-batzelladine D and (+)-batzelladine A with excellent stereocontrol.
The synthesis of di(hydroxyalkyl) substituted bicyclic guanidines
Madder, A.,Muenster, I.,Rolle, U.,Clercq, P. J. De
, p. 613 - 622 (2007/10/03)
The synthesis of the enantiomerically pure bicyclic guanidines 3a and 3b is described.The convergent strategy is based on methodology developed by Schmidtchen.The therefore required amine components 6 and 9 obtained from methionine and L-glutamic acid, respectively.
Synthesis of a Chiral Di(hydroxyalkyl) Substituted Bicyclic Guanidine
Muenster, Ingo,Rolle, Ulrike,Madder, Annemieke,Clerq, Pierre J. De
, p. 2673 - 2674 (2007/10/03)
Schmidtchen's methodology is used successfully for the synthesis of the chiral disubstituted bicyclic guanidinium salt 2.The two therefore required primary amine compounds 6 and 9 are obtained from L-methionine and L-glutamic acid, respectively.
Process for preparing 5-vinyl-2-pyrrolidinone and intermediates therefor
-
, (2008/06/13)
4-Amino-5-hexenoic acid is prepared by: (a) reacting 5-oxo-2-pyrrolidine-acetonitrile with hydrogen and dimethylamine in the presence of a palladium catalyst to form N,N-dimethyl-2-[5'-oxo-2'-pyrrolidine]ethylamine; (b) oxidizing N,N-dimethyl-2-[5'-oxo-2'-pyrrolidine]-ethylamine to produce the corresponding N-oxide derivative; (c) pyrolysis of the N-oxide derivative to form 5-vinyl-2-pyrrolidinone; (d) optionally, separating N,N-dimethyl-2-[5'-oxo-2'-pyrrolidine]ethylamine by-product from the 5-vinyl-2-pyrrolidinone product; and (e) hydrolyzing 5-vinyl-2-pyrrolidinone to form 4-amino-5-hexenoic acid.
