Keywords: Amino acid methyl ester hydrochlorides; amino acids; trimethylchlorosilane; esterification. This method is not only compatible with natural aminoacids, but also with other aromatic and aliphatic amino acids.Amino acid methyl esters are important intermediates in organic synthesis, which have been used in various areas such as peptide synthesis [,A variety of reagents have been reported for the transformation of amino acids into amino acid methyl esters, which include protic acids (gaseous hydrochloric acid [,The synthesis of acid methyl ester hydrochlorides is shown in,Compared with other methods, the yields obtained with the TMSCl/MeOH system were in most cases comparable to or even higher than those obtained with the thionyl chloride/MeOH and HCl(SO.In general, two equivalents of TMSCl were used. In general the reaction time was 12 h. Because of the poor solubility in methanol of both of substrates and products in entries 1, 2, 13, 14, 19, the reaction time for these substrates was 24 h.Racemization is a common problem in the synthesis of amino acid esters.

Amino acid methyl esters are im portant intermediate s in organic synthesis, which have been used in various areas such as peptide synthesis, medi cinal chemistry [2-3], as chiral sources …
Then methanol (100 mL) was added and the resulting solution or suspension was stirred at room temperature.
A series of amino acids, including natural amino acids, aromatic amino acids and aliphatic amino acids was transformed to corresponding amino acid methyl ester hydrochlorides in good to excellent yields, which are summarized in Table 1. The synthesis of acid methyl ester hydrochlorides is shown in Scheme 1.
Freshly distilled chlorotrimethylsilane (0.2 mol) was added slowly and stirred with a magnetic stirrer. This occurs with good diastereo- and enantioselectivity to yield β-amino esters 2 and 3 (after hydrogenolysis of the N-chiral group).A model is reported for the origin of the stereoselectivity through an enol ester−diacetoxyborohydride 6, which affords the intramolecular reduction.
