  • Patent number: 6472542
    Abstract: Simvastatin is produced from lovastatin in high yield and in pharmaceutical purity by forming an amide of lovastatin and protecting the free hydroxyl groups of the lovastatin amide with hexamethyidisilazane (HMDS) to form a protected lovastatin amide. The &agr;-carbon of the 2-methylbutyrate secondary chain of the protected lovastatin amide may be methylated to form a protected simvastatin amide. The protecting groups may be removed therefrom by quenching the methylation reaction with water. The simvastatin amide which is obtained may be hydrolyzed to form simvastatin acid, followed by forming a simvastatin ammonium salt, lactonizing the salt to form simvastatin, and recrystallizing the thus formed crude Simvastatin to a high degree of purity. The HMDS protecting agent for the lactone hydroxyl groups of Lovastatin is selected so as to result in a reaction that does not produce acid so that a base, such as imidazole, is not required to neutralize the acidity of the reaction medium.

  • Patent number: 6348615
    Abstract: A process for producing (2R, 3S)-3-amino-4-phenylbutane-1,2-epoxide compounds which comprises treating a (2S, 3S)-3-amino-1-halo-2-hydroxy-4-phenylbutane compound or a (2S, 3S)-3-amino-4-phenylbutane-1,2-epoxide with a carboxylic acid quaternary ammonium salt or a carboxylic acid metal salt a quaternary ammonium salt and a quaternary ammonium salt, to give a (2S, 3S)-1-acyloxy-3-amino-2-hydroxy-4-phenylbutane compound, further treating the same with a sulfonic acid halide in the presence of an organic base to give a (2S, 3S)-1-acyloxy-3-amino-2-sulfonyloxy-4-phenylbutane compound, furthermore treating said compound with an inorganic base. An intermediate for the production of an HIV protease inhibitor can be produced from L-phenylalanine.

  • Patent number: 6271398
    Abstract: A process for the production of simvastatin and its analogues that is efficient, economical and convenient involves the use of hydroxyl protected intermediates of formula (III) or (VII). These intermediates allow for direct alkylation of the butyrate side chain followed by deprotection and reformation of the lactone ring. R1 is hydrogen or methyl; R2 represents a straight or branched chain alkyl group having 1 to 8 carbon atoms, a cycloalkyl group having 3 to 7 carbon atoms, or an aralkyl group having 1 to 6 carbon atoms in the alkyl chain; R3 and R4 each independently represent an alkyl group, an ether group, a thioether group, an aryl group, an aralkyl group, an alkenyl group, a cyclic ether group, or a cyclic thioether group; and R5 and R6 each independently represent hydrogen, an alkyl group, an aryl group, an aralkyl group, an alkoxy group, or an ether group.
