The Schöllkopf Chiral Auxiliary (109838-85-9): (R)-2,5-Dihydro-3,6-dimethoxy-2-isopropylpyrazine
a-Amino acids are important targets for the medicinal and biotechnology fields and their optical purity is an important factor in biological activity. In the early 1980s Schöllkopf developed a method to produce optically pure a-amino acids that involved diastereoselective alkylation of a masked glycine.1
(R)-2,5-Dihydro-3,6-dimethoxy-2-isopropylpyrazine (product code FD04039, Cas No 109838-85-9) is now known as a Schöllkopf chiral auxiliary.
