Patent Number Title Of Patent Date Issued
7495123 Process for the preparation of enantiomerically enriched beta amino acid derivatives February 24, 2009
The present invention relates to a process for the efficient preparation of enantiomerically enriched beta amino acid derivatives wherein the amino group is unprotected. The product chiral beta amino acid derivatives are useful in the asymmetric synthesis of biologically active molec
7468459 Process for the preparation of chiral beta amino acid derivatives by asymmetric hydrogenation December 23, 2008
The present invention relates to a process for the efficient preparation of enantiomerically enriched beta amino acid derivatives which are useful in the asymmetric synthesis of biologically active molecules. The process comprises an enantioselective hydrogenation of a prochiral beta ami
6835860 Iodohydroxylation of olefins December 28, 2004
Iodohydroxylated olefins can be prepared by treating an olefin with an aqueous solution of an iodine monohalide selected from iodine monochloride and iodine monobromide.
6603013 Heterogeneously catalyzed process for cross coupling alkenyl halides with boronic acids August 5, 2003
The present invention relates to a process wherein heterogeneous finely-dispersed palladium catalysts are used in a cross-coupling reaction of alkenyl halides and aryl or heteroaryl boronic acids in the presence of base in an aprotic solvent to produce aryl- or heteroaryl-olefin compound
6025500 Stereoselective process for enalapril February 15, 2000
The invention relates to an improved stereoselective heterogenous catalytic reductive amination between ethyl 2-oxo-4-phenylbutyrate and alanylproline using hydrogen, a catalyst and one or more additives to produce the ACE inhibitor, enalapril.
