Enantioselective synthesis of both enantiomers of 2-amino-6-phosphonohexanoic acid [(R)- and (S)-AP6], a potent and specific agonist of AMPA receptor subtype

, p. 1511 - 1514 (1997)
The preparation of both enantiomers of 2-amino-6-phosphonohexanoic acid [(R)- and (S)-AP6] is described. The highly diastereoselective alkylation of imidazolidinones 4 and hydrolysis of the alkylated products [(2R,5R,1'S)-6 and (2S,5S,1'S)-6] proceeds under relatively mild conditions to give the physiologically important, enantiopure aminophosphonic acids (R)-AP6 and (S)-AP6.

Paragraph 0102; 0106, (2019/03/28)
PROBLEM TO BE SOLVED: To provide an involucrin gene expression promoter that has high effect of promoting involucrin gene expression, and is applied to the skin, to quickly increase involucrin concentrations, and markedly improving the barrier function. SOLUTION: An involucrin gene expression promoter contains at least one selected from a compound represented by the following formula (1) [where R1 and R2 are the same or different to represent a hydrogen atom, or a substituent. n is an integer of 1 or greater], a salt thereof, and their hydrates as an active ingredient.

PHOSPHORUS-CONTAINING AMINOCARBOXYLIC ACIDS. COMMUNICATION IV. A CONVENIENT METHOD OF PHOSPHONIC ACIDS SYNTHESIS
Ragulin, V. V.,Bofanova, M. E.,Tsvetkov, Eugene N.
, p. 237 - 242 (2007/10/02)
The communication is concerned with the synthesis of phosphonic aminocarboxylic acids by phosphorylation of diethyl ω-halogen alkyl acetamidomalonates with tris(trimethylsilyl) phosphite, followed by alcoholysis and acid hydrolysis of the resulting intermediate esters.Key words: Phosphonic aminocarboxylic acids; tris(trimethylsilyl) phosphite; ω-halogenalkyl acetamidomalonates; phosphorylation; alcoholysis, hydrolysis
