An efficient synthesis of (S)-m-tyrosine

An efficient synthesis of (S)-m-tyrosine. Bender, David M.; Williams, Robert M. (Department of Chemistry, Colorado State University, Fort Collins, CO 80523, USA). Journal of Organic Chemistry, 62(19), 6690-6691 (English) 1997 American Chemical Society. CODEN: JOCEAH. ISSN: 0022-3263. DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) Section cross-reference(s): 25 A very simple and convenient procedure that can be used to prep.In this article, certain chemicals are used. One of their cas registry numbers is 1700-30-7 1700-30-7 is the cas registry number of certain chemical which is used as reagents here. either (S)- or (R)-m-tyrosine is reported. The optically active starting material oxazinone I (Cbz = CO2CH2Ph) was condensed with m-(benzyloxy)benzyl bromide via formation of sodium enolate using NaHMDS in THF at -78°. The alkylation product II (Bn = CH2Ph) was obtained in 87% yield with a diastereomeric excess of >95%. The final product, (S)-m-tyrosine, was obtained from the benzylated oxazinone II by catalytic hydrogenation in 74% overall yield with an enantiomeric excess of >96%. ..
