Ethyl N-[(benzyloxy)carbonyl]leucylglycinate is a complex organic compound with the chemical formula C21H29N2O5. It is a derivative of leucylglycinate, an amino acid dipeptide, where the leucine residue is protected by a benzyloxycarbonyl (Z) group, and the glycine residue is esterified with an ethyl group. ethyl N-[(benzyloxy)carbonyl]leucylglycinate is often used as a building block in peptide synthesis, particularly in the solid-phase peptide synthesis (SPPS) method, where the Z group serves as a temporary protecting group for the amino group of leucine, preventing unwanted side reactions during the synthesis process. The ethyl ester group is used to facilitate the cleavage of the peptide from the solid support after the synthesis is complete.

Check Digit Verification of cas no

The CAS Registry Mumber 2867-06-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,6 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2867-06:
(6*2)+(5*8)+(4*6)+(3*7)+(2*0)+(1*6)=103
103 % 10 = 3
So 2867-06-3 is a valid CAS Registry Number.

Facile and purification free synthesis of peptides utilizing ROMPgel- and ROMPsphere-supported coupling reagents

Barrett, Anthony G.M.,Bibal, Brigitte,Hopkins, Brian T.,K?bberling, Johannes,Love, Andrew C.,Tedeschi, Livio

, p. 12033 - 12041 (2005)

5-Norbornene-2-carboxaldehyde and norbornadiene were respectively converted into norbornene derivatives functionalized with fluoroformamidinium hexafluorophosphate and 2-bromo-N-methylpyridinium tetrafluoroborate residues. Both these norbornene monomers were ring opening metathesis polymerized or graft copolymerized onto polystyrene cores to produce ROMPgel and ROMPsphere peptide-coupling reagents. These were used to prepare hindered amides, dipeptides and tripeptides with minimal purification in parallel arrays.

Organophosphorus esters of 1-hydroxy-2-phenylbenzimidazole: Synthesis and utilization as novel peptide coupling reagents

Kokare, Nagnnath D.,Nagawade, Rahul R.,Rane, Vipul P.,Shinde, Devanand B.

, p. 766 - 772 (2008/01/04)

Highly efficient coupling reagents - phosphoric acid diethyl ester 2-phenylbenzimidazol-1-yl ester, diphenylphosphinic acid 2-phenylbenzimidazol-1- yl ester and phosphoric acid diphenyl ester 2-phenylbenzimidazol-1-yl ester - were designed, synthesized and successfully applied in peptide coupling reactions. Their efficiency was evaluated through the synthesis of a range of amides and peptides, and the extent of racemization was studied by HPLC and found to be negligible. The mechanism of action is probably similar to those found for organophoshorus esters of hydroxybenzotriazole: a presumption supported by the isolation and characterization by mass spectrometry and 1H NMR of some of the proposed intermediates.

Circular dichroism studies on absolute configuration assignment of peptidomimetics with a terminal chiral 3-arylpropionic acid unit

Frelek, Jadwiga,Fryszkowska, Anna,Kwit, Marcin,Ostaszewski, Ryszard

, p. 2469 - 2478 (2007/10/03)

The relationship between the molecular structure of peptidomimetics 1 and their chiroptical properties has been studied using circular dichroism spectroscopy. It was demonstrated that the sign of the Cotton effects occurring around 230 and 270 nm enables the direct assignment of stereochemistry at C-1 and C-3 carbon atoms. The TD-DFT calculations of the circular dichroism (CD) spectrum of one of the model compounds confirm the absolute stereochemistry assignment made experimentally. Thus, CD spectroscopy proved to be a simple, reliable and general tool for the determination of the absolute configuration of the stereogenic centers of peptidomimetics with a terminal 3-arylpropionic group.

A new method for the synthesis of carboxamides and peptides using 1,1′-carbonyldioxydi[2(1H)-pyridone] (CDOP) in the absence of basic promoters

Shiina, Isamu,Kawakita, Yo-Ichi

, p. 1951 - 1955 (2007/10/03)

Various carboxamides or peptides are synthesized from the corresponding carboxylic acids and amines or α-amino acids using 1,1′-carbonyldioxydi[2(1H)-pyridone]. The reaction proceeds in the absence of basic promoters such as triethylamine or 4-(dimethylamino)pyridine, therefore, the undesired racemization does not occur at all in the segment coupling producing Z-Gly-Phe-Val-OMe and Z-Phe-Val-Ala-OMe.

New system for peptide synthesis using N-acylpyrazoles

Kashima, Choji,Tsuruoka, Shiro,Mizuhara, Saori

, p. 413 - 424 (2007/10/03)

New system of peptide synthesis was described. The extension of one amino acid unit on the peptide chain was constituted from only 2 reaction steps, the conversion from esters to the corresponding N-acylpyrazoles and the subsequent aminolysis with amino esters. This new system was distinctive from the conventional peptide synthesis, which was consisted of 3 steps of the deprotection, the activation and the condensation. Moreover, the key intermediate N-acylpyrazoles exhibited the excellent properties of high sensitivity and separability for the chiral column on HPLC using the UV detector.

A convenient method for the preparations of carboxamides and peptides by using di(2-pyridyl) carbonate and O,O′-di(2-pyridyl) thiocarbonate as dehydrating reagents

Shiina,Suenaga,Nakano,Mukaiyama

, p. 2811 - 2818 (2007/10/03)

Preparations of carboxamides and peptides are performed in high yields from free carboxylic acids and amines by dehydration condensation using di(2-Pyridyl) carbonate (DPC) or O,O′-Di(2-Pyridyl) thiocarbonate (DPTC) in the presence of a catalytic amount of 4-(dimethylamino)pyridine (DMAP). The formation of 2-Pyridyl esters, key intermediates of the reaction, from carboxylic acids by using DPC proceeded faster than by using DPTC; therefore, the former carbonate is more efficiently employed in the above condensation reactions.

Preparation of carboxamides via carboxylic-phosphoric anhydrides

Gaede, Bruce

, p. 92 - 93 (2013/09/08)

A number of reagents used to prepare carboxamides via a carboxylic-phosphoric anhydride intermediate have been reexamined. It was found that a simple carboxylic-phosphoric anhydride prepared from a carboxylic acid and commercially available diethyl chlorophosphate provided several significant advantages over more complex intermediates in many cases.
