- Synthesis of (R) and (S)-aminocarnitine, (R) and (S)-4-phosphonium-3-amino-butanoate, (R) and (S) 3,4-diaminobutanoic acid, and their derivatives starting from D- and L-aspartic acid
-
R or S aminocarnitine, R or S phosphonium aminocarnitine and R and S 3,4 diaminobutanoic acid, and their derivatives are prepared using starting from aspartic acid with the same configuration as the desired compounds. This process is advantageous from the industrial point of view in terms of the type of reactants used, the reduced volumes of solvents and the possibility of avoiding purification of the intermediate products.

- Synthesis of (R) and (S) -aminocarnitine and their derivatives starting from D- and L-aspartic acid
-
R or S aminocarnitine and their derivatives with formula (I) where Y is as described in the description, starting with aspartic acid with the same configuration as the aminocarnitine desired. This process has advantage in the type of reactants used, reduced volumes of solvents and the possibility of avoiding purification of intermediate products.

- A Practical and Stereoconservative Synthesis of (R)-3-Amino-4-(trimethyl-ammonio)butanoate [(R)-Aminocarnitine], and Its Trimethylphosphonium and Simple Ammonium Analogues Starting from D-Aspartic Acid
-
We have developed a new stereospecific synthesis of (R)-aminocarnitine using D-aspartic acid as the starting material. This strategy, which is simple and amenable to an industrial scale-up, gives the target compound in six steps and in fairly good overall
