Total synthesis of Monatin and the taste expression

Total synthesis of Monatin and the taste expression. Nakamura, Kozo; Kogiso, Kana; Nakajima, Takero; Kayahara, Hiroshi (Graduate School of Agriculture, Shinshu University, Nagano 399-4598, Japan). Peptide Science, Volume Date 2004, 40th, 61-64 (English) 2003 Japanese Peptide Society. CODEN: PSCIFQ. ISSN: 1344-7661. DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) Section cross-reference(s): 17, 22 A symposium report. A natural sweet peptidomimetic, Monatin, (2S,4S)-4-(indol-3-yl-methyl)-glutamic acid, was synthesized. Two chiral centers on it were regulated by diastereoselective alkylation using a chiral aldehyde. 102308-32-7 and 823814-91-1 are also in the experiment. Synthetic Monatin exhibits a sweet potency equal to that of the natural product. Taste expressions of Monatin and diastereomer with the (2R,4S)-configuration can be well understood by the structure-taste relationships proposed by M. Goodman et al. Computer simulation studies indicate that the sweetness of Monatin is expressed by 4-COOH (B), 4-NH (AH), and the indole ring on the L-shape structure. .

ISSN: 0040-4039. DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) Section cross-reference(s): 28 L-Serine derived E- and Z-enoates I were subjected to catalytic dihydroxylation and hydrogenation reactions. The obsd. selectivities can be explained to arise from 1,3-allylic strain. ..
