标题:Process for synthesis of amidoacids using a cobalt catalyst and a bidental phosphine ligand
发明人：LIN JIANG-JEN
权利人:TEXACO INC
摘要:A process is disclosed for producing N-acetyl-aminoacid which comprises reacting a feedstock from the group consisting of simple olefins, acetamide and synthesis gas with a catalyst comprising a cobalt-containing compound promoted by a bidental-phosphine ligand in a solvent at a pressure of 500 psi or greater and a temperature of 50 DEG C. or greater. The presence of the ligand increases both reaction rate and cobalt catalyst stability.

摘要:Stereoselective synthesis of 3,4-diamino-1,2-diols possessing a long hydrocarbon chain was carried out via olefin cross-metathesis between a commercial tetradec-1-ene and known diastereoisomeric trichloroacetamides prepared in our laboratory. Subsequent modification of the obtained coupling products used an approach based on functional group interconversions, which was accompanied by the rational choice of deprotection protocols. The resulting molecules represent novel isomeric amino analogues of natural D-ribo-phytosphingosine, which on the basis of their structure could have the status of skin sphingomimetics, i.e. substances that can affect the properties of the skin and dermis in terms of improving the quality of the lipid matrix (e.g. change in permeability, hydration), or stimulating the biosynthesis of procollagen in deeper structures. The cytotoxic effect of the prepared aminoisophytosphingosines was examined on two human non-malignant cell lines (BJ and HaCaT) and the screening results confirmed the safety in at least three representatives of the prepared series of compounds. In addition, the ability of the synthesized derivatives to inhibit cancer cell proliferation was also investigated. The results of preliminary anticancer screening showed weaker antiproliferative potential of these unusual sphingoid bases.
