20696-57-5 Usage

Definition

ChEBI: An amino acid amide that is the carboxamide of L-tryptophan.

Check Digit Verification of cas no

The CAS Registry Mumber 20696-57-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,9 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20696-57:
(7*2)+(6*0)+(5*6)+(4*9)+(3*6)+(2*5)+(1*7)=115
115 % 10 = 5
So 20696-57-5 is a valid CAS Registry Number.

Cyclic hexapeptide dimers, antatollamides A and B, from the ascidian Didemnum molle. A tryptophan-derived auxiliary for L- and D-amino acid assignments

Salib, Mariam N.,Molinski, Tadeusz F.

, p. 10181 - 10187 (2017)

Two dimerized cyclic hexapeptides, antatollamides A 1 and B (2), were isolated from the colonial ascidian Didemnum molle collected in Pohnpei. The amino acid compositions and sequences were determined by interpretation of MS and 1D and 2D NMR data. Raney Ni reduction of antatollamide A cleaved the dimer to the corresponding monomeric cyclic hexapeptide with replacement of Cys by Ala. The amino acid configuration of 1 was established, after total hydrolysis, by derivatization with a new chiral reagent, (5-fluoro- 2,4-dinitrophenyl)-Nα-L-tryptophanamide (FDTA), prepared from L-Trp, followed by LCMS analysis; all amino acids were found to be L-configured except for D-Ala.

Synthetic method for chiral alpha-aminoamide compounds

-

Paragraph 0053; 0054; 0056, (2018/01/11)

The invention provides a synthetic method for chiral alpha-aminoamide compounds, belongs to the technical field of organic synthetic methodology, and concretely relates to a synthetic method for chiral alpha-aminoamide compounds, wherein the method has a simple process, low costs and good economy. The method comprises the following steps: 1, performing ammonolysis: adding substituted chiral alpha-aminocarboxylate hydrochloride into concentrated ammonia water, performing stirring for 4-12h under a room temperature, wherein each 1mmol substituted chiral alpha-aminocarboxylate hydrochloride is corresponding to 2-8mL the concentrated ammonia water; 2, after a reaction is finished, performing distillation for removing ammonia water after the reaction to obtain crude products chiral alpha-aminoamide compounds; and 3, performing filtration on the obtained crude products chiral alpha-aminoamide compounds by adopting a manner of adding a solvent or performing purification on the obtained crude products chiral alpha-aminoamide compounds through a manner of column chromatography which uses ammonia water as a mobile phase to obtain the products chiral alpha-aminoamide compounds. Compared with the prior art, a large number of an ammonia gas for ammonolysis is not needed in the method, the process and post-treatment are simple, costs are low and reaction time is short.
