Check Digit Verification of cas no

The CAS Registry Mumber 2899-07-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,9 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2899-07:
(6*2)+(5*8)+(4*9)+(3*9)+(2*0)+(1*7)=122
122 % 10 = 2
So 2899-07-2 is a valid CAS Registry Number.

Synthesis of N-Benzyloxycarbonyl-N-methylaminoacids from Oxazolidine-5-one Derivatives

Chipens, G. I.,Slavinskaya, V. A.,Sile, D. E.,Korchagova, E. Kh.,Katkevich, M. Yu.,Grigor'eva, V. D.

, p. 576 - 578 (1992)

Hydrogenolysis of 3-benzyloxycarbonyloxazolidine-5-one and 3-benzyloxycarbonyl-4-benzyloxazolidine-5-one by Et3SiH in the presence of F3CCO2H is demonstrated to be a convenient method for preparing substituted N-methylaminoacids.In contrast with catalytic

Design, synthesis, and optimization of balanced dual NK1/NK 3 receptor antagonists

Hanessian, Stephen,Jennequin, Thomas,Boyer, Nicolas,Babonneau, Vincent,Soma, Udaykumar,Mannoury La Cour, Clotilde,Millan, Mark J.,De Nanteuil, Guillaume

supporting information, p. 550 - 555 (2014/06/09)

In connection with a program directed at potent and balanced dual NK 1/NK3 receptor ligands, a focused exploration of an original class of peptidomimetic derivatives was performed. The rational design and molecular hybridization of a novel phenylalanine core series was achieved to maximize the in vitro affinity and antagonism at both human NK1 and NK3 receptors. This study led to the identification of a new potent dual NK1/NK3 antagonist with pKi values of 8.6 and 8.1, respectively.

Enantioselective direct α-amination of aldehydes via a photoredox mechanism: A strategy for asymmetric amine fragment coupling

Cecere, Giuseppe,Koenig, Christian M.,Alleva, Jennifer L.,MacMillan, David W. C.

supporting information, p. 11521 - 11524 (2013/09/02)

The direct, asymmetric α-amination of aldehydes has been accomplished via a combination of photoredox and organocatalysis. Photon-generated N-centered radicals undergo enantioselective α-addition to catalytically formed chiral enamines to directly produce stable α-amino aldehyde adducts bearing synthetically useful amine substitution patterns. Incorporation of a photolabile group on the amine precursor obviates the need to employ a photoredox catalyst in this transformation. Importantly, this photoinduced transformation allows direct and enantioselective access to α-amino aldehyde products that do not require postreaction manipulation.

Synthesis of N-methyl L-phenylalanine for total synthesis of pepticinnamin e

The concise and efficient preparation of them in large scale was developed and 3, 10 and 11 were obtained in suitable form used for both nitrogen-end and oxygen-end extension in next coupling reaction in peptides synthesis, specifically in total synthesis of natural pepticinnamin E.

Total synthesis and biological evaluation of tamandarin B analogues

Adrio, Javier,Cuevas, Carmen,Manzanares, Ignacio,Joullie, Madeleine M.

, p. 5129 - 5138 (2008/02/07)

(Chemical Equation Presented) Tamandarins A and B are a class of marine natural cyclodepsipeptides with structures and biological activities closely related to those of the didemnins. The easier synthetic access to tamandarins accelerates the preparation of new macrocyclic derivatives of this family of antitumor, antiviral, and immunosuppressive compounds. The optimization of the previously reported synthetic route to tamandarins by changing the macrolactamization site from Nst1 and Thr6 to Pro 4 and N,O-Me2Tyr5 residues led to a significant improvement in the reaction yield. Using this new synthetic approach, four new macrocyclic analogues of tamandarin B were prepared and evaluated for anticancer activity. These results provide further insight into the structure-activity relationship of the tamandarins and didemnins.

A total synthesis of ulongamide A (1), a cytotoxic natural cyclic depsipeptide, was achieved by a convergent route involving coupling of the fragments 7 and 8 to the pentapeptide 24, and subsequent cyclization thereof after prior removal of the t-Boc protecting groups.

Effective methods for the synthesis of N-methyl β-amino acids from all twenty common α-amino acids using 1,3-oxazolidin-5-ones and 1,3-oxazinan-6-ones

Hughes, Andrew B.,Sleebs, Brad E.

, p. 2611 - 2637 (2007/10/03)

N-Methyl β-amino acids are generally required for application in the synthesis of potentially bioactive modified peptides and other oligomers. Previous work highlighted the reductive cleavage of 1,3-oxazolidin-5-ones to synthesise N-methyl α-amino acids. Starting from α-amino acids, two approaches were used to prepare the corresponding N-methyl β-amino acids. First, α-amino acids were converted to N-methyl α-amino acids by the so-called '1,3-oxazolidin-5-one strategy', and these were then homologated by the Arndt-Eistert procedure to afford N-protected N-methyl β-amino acids derived from the 20 common α-amino acids. These compounds were prepared in yields of 23-57% (relative to N-methyl α-amino acid). In a second approach, twelve N-protected α-amino acids could be directly homologated by the Arndt-Eistert procedure, and the resulting β-amino acids were converted to the 1,3-oxazinan-6-ones in 30-45% yield. Finally, reductive cleavage afforded the desired N-methyl β-amino acids in 41-63% yield. One sterically congested β-amino acid, 3-methyl-3-aminobutanoic acid, did give a high yield (95%) of the 1,3-oxazinan-6-one (65), and subsequent reductive cleavage gave the corresponding AIBN-derived N-methyl β-amino acid 61 in 71% yield (Scheme 2). Thus, our protocols allow the ready preparation of all N-methyl β-amino acids derived from the 20 proteinogenic α-amino acids.

The Dakin-West reaction of N-alkoxycarbonyl-N-alkyl-α-amino acids employing trifluoroacetic anhydride

Kawase, Masami,Hirabayashi, Michitaka,Kumakura, Hiroko,Saito, Setsuo,Yamamoto, Katsumi

, p. 114 - 119 (2007/10/03)

The Dakin-West reaction of N-alkoxycarbonyl-N-alkyl-α-amino acids (1a - j) with trifluoroacetic anhydride in the presence of pyridine gave α-amido trifluoromethyl ketones (2a - j), in which probable intermediates were mesoionic 1,3-oxazolium-5-olates (munchnones). The diastereoselective reduction of 2a - f with NaBH4 gave the threo-aminoalcohols (5a - f), which may be explained by the Felkin-Anh model. This was confirmed by converting 5a - f into trans-5-trifluoromethyl-2-oxazolidinones (6a - f) in good yields.
