  • Synthesis of N-[N-(3,3-dimethylbutyl)-L-?-aspartyl]-L-phenylalanine 1-methyl ester using 3,3-dimethylbutyraldehyde precursors
    Patent number: 8034969
    Abstract: N—[N-(3,3-dimethylbutyl)-L-?-aspartyl]-L-phenylalanine 1-methyl ester is produced by hydrogenation of L-?-aspartyl-L-phenylalanine 1-methyl ester and 3,3-dimethylbutyraldehyde produced in situ by the hydrolysis or cleavage of a 3,3-dimethylbutyraldehyde precursor. The production method is efficient and low cost, as compared with conventional N—[N-(3,3-dimethylbutyl)-L-?-aspartyl]-L-phenylalanine 1-methyl ester synthesis.
    Type: Grant
    Filed: May 12, 2010
    Date of Patent: October 11, 2011

  • Catalyst system for aerobic oxidation of primary and secondary alcohols
    Patent number: 7351867
    Abstract: The present invention relates to a process of oxidation of alcohols selectively to aldehydes or ketones with molecular oxygen using a TEMPO based catalyst, Fe-bipyridyl or Fe-phenantroline co-catalyst and N-bromosuccinimide promoter in acetic acid solvent. The oxidation takes places at high rates and high aldehyde selectivity at temperatures in the range 45-50° C. and oxygen or air pressures of 0-15 psi. The alcohol conversion of 95-100% and aldehyde selectivity higher than 95% are achieved over 3-4 hours reaction time. Aldehydes such as 3,3-dimethyl-1-butanal can be produced efficiently using the present invention.

  • Bromine free TEMPO based catalyst system for oxidation of primary and secondary alcohols using NaOCl as an oxidant
    Patent number: 6825384
    Abstract: The present invention relates to a process of oxidation of alcohols selectively to aldehydes or ketones with NaOCl using a TEMPO—borate catalyst system. It is shown that the oxidation can be efficiently carried out without KBr additives under solvent free conditions. Aldehydes such as 3,3-dimethylbutyraldehyde can be produced efficiently using the present invention.
