  • Patent number: 7429680
    Abstract: Severely sterically hindered secondary aminoether alcohols are prepared by reacting an organic carboxylic acid or alkali metal salt of an organic carboxylic acid with a sulfonyl halide, a sulfuryl halide, a mixed sulfuryl ester halide or a mixed sulfuryl amide halide to yield a sulfonic-carboxylic anhydride compound which is then reacted with a dioxane to cleave the ring of the dioxane, yielding a cleavage product which cleavage product is then aminated with an alkylamine and hydrolyzed with base to yield the severely sterically hindered secondary aminoether alcohol.

  • Patent number: 6794542
    Abstract: Process for the preparation of a diasteromerically enriched phenylglycine amide derivative in which an enantiomerically enriched phenylglycine amide is converted into the corresponding Schiff base with the aid of compound R2—C(O)—R3, and the Schiff base obtained is subsequently converted into the diastereomerically enriched phenyglycine amide derivative with the aid of a cyanide source, a reducing agent or an allyl organometallic compound. The phenylglycine amide derivatives obtained are interesting starting materials for the preparation of for example enantiomerically enriched &agr;- and or &bgr;-amino acids and derivatives thereof, such as amides and esters, and amines.
