  • Publication number: 20140303344
    Abstract: The invention relates to a process for the stereoselective preparation of amino acid derivatives, comprising a hydrogenation reaction of the compound of formula (III), alternatively its enantiomer, wherein R is (C1-C8)-alkyl; followed by a hydrolysis reaction to obtain L-mesityl alanine, alternatively its enantiomer D-mesityl alanine and, optionally, subjecting said compound to an amino group protection reaction, particularly as Fmoc. It also comprises Fmoc-L- or Fmoc-D- mesityl alanine as products per se, useful as intermediates in preparing peptides or peptide analogs with therapeutic or biological activity.

  • Patent number: 8093398
    Abstract: It comprises a process for the production of delmopinol or a pharmaceutically acceptable salt and/or a solvate thereof, by subjecting the compound of formula (II) where R1 and R2 are the same or different, independently selected from the group consisting of H, (C1-C6) alkyl or, alternatively, R1 and R2 form, together with the carbon atom to which they are attached, a (C5-C6) cycloalkyl radical; and R3 is a radical selected from the group consisting of CF3, (C1-C4) alkyl, phenyl, and phenyl mono- or disubstituted by a radical selected from the group consisting of (C1-C4)-alkyl, halogen and nitro to a deprotection and cyclisation reaction. The process is useful to prepare delmopinol or its salts on an industrial scale. The compound of formula (II) is new and also forms part of the present invention, as well as its preparation process and other new intermediates of said preparation process.

  • Publication number: 20090124577
    Abstract: It comprises new substituted 4-valinylmethylphenyl boronic acids of formula (II) and their derivatives and also its preparation process. It also comprises a preparation process of Valsartan (I) from such intermediates. The process comprises the reaction of the new 4-valinylmethylphenyl boronic compounds with a (halophenyl)tetrazole compound which proceeds with high yields. The process is particularly advantageous in its practical industrial realization because it avoids the use of azide derivatives and also the use of expensive biphenyl intermediates.
