Check Digit Verification of cas no

The CAS Registry Mumber 5211-23-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5211-23:
(6*5)+(5*2)+(4*1)+(3*1)+(2*2)+(1*3)=54
54 % 10 = 4
So 5211-23-4 is a valid CAS Registry Number.

An efficient, stereocontrolled and versatile synthetic route to bicyclic partially saturated privileged scaffolds

Bond, Andrew D.,Hanby, Abigail R.,King, Thomas A.,Moss, Thomas A.,Sore, Hannah F.,Spring, David R.,Stewart, Hannah L.

supporting information, p. 6818 - 6821 (2020/07/04)

Herein, we describe the development of a simple, high yielding and stereocontrolled strategy for the synthesis of a series of triazolopiperazines and other biologically relevant fused scaffolds from optically active amino acids. This route was applied to the synthesis of 22 scaffolds containing new, previously inaccessible vectors and used to access a novel analogue of ganaplacide.

Efficient synthesis of methyl (S)-4-(1-methylpyrrolidin-2-YL)-3-oxobutanoate as the key intermediate for tropane alkaloid biosynthesis with optically acitve form

Katakam, Nanda Kumar,Seifert, Cole W.,D'Auria, John,Li, Guigen

, p. 604 - 613 (2019/08/01)

Methyl (S)-4-(1-methylpyrrolidin-2-yl)-3-oxobutanoate has been synthesized for enzymatic studies on cyclization enzymes during cocaine biosynthesis in Erythroxylum coca plants. During the present new synthesis, L-proline was first protected with Cbz group and reduced to chiral amino alcohol, which were then followed by Swern oxidation, Wittig reaction and decarboxylative condensation. At the last step, N-methylamino acid precursor was treated with 1,1'-carbonyldiimidazole followed by reacting with methyl potassium malonate to give the 3-oxobutanoate in 54% overall yield. This new strategy has proven to avoid obvious racemization of the L-proline chiral center during the synthesis. In addition, six of the eight synthesis steps were performed via GAP chemistry/technology without the use of column chromatography for purification.

Iminium Catalysis inside a Self-Assembled Supramolecular Capsule: Modulation of Enantiomeric Excess

Br?uer, Thomas M.,Zhang, Qi,Tiefenbacher, Konrad

, p. 7698 - 7701 (2016/07/07)

The noncovalent combination of a supramolecular host with iminium organocatalysis is described. Due to cation–π interactions the reactive iminium species is held inside the host and reacts in this confined environment. The products formed differ up to 92 % ee from the control experiments without added host. A model rationalizing the observed difference is presented.

A lanthanide(III) triflate mediated macrolactonization/solid-phase synthesis approach for depsipeptide synthesis

Goodreid, Jordan D.,Dos Santos Da Silveira, Eduardo,Batey, Robert A.

, p. 2182 - 2185 (2015/05/13)

The effect of dysprosium(III) triflate on macrolactonization reactions to form depsipeptides using MNBA (Shiina's reagent) is reported. Improved yields were obtained for the formation of 16-membered depsipeptides using lanthanide triflate additives. The use of a macrocyclization strategy permits the use of a semiautomated solid-phase synthesis approach for the rapid synthesis of analogues of the antibacterial A54556 acyldepsipeptides in only two physical operations, requiring only final product purification after cyclization.

Practical one-pot double functionalizations of proline

Huy, Peter,Schmalz, Hans-Guenther

experimental part, p. 954 - 960 (2011/05/07)

Solubilization of proline as the triethylammonium salt allows N-protection (as the Boc, Cbz or Moc derivative) and subsequent esterification or amidation of the carboxy terminus to be performed in an efficient one-pot fashion. Based on this concept, highly practical protocols were developed to prepare a series of proline derivatives (including Pro-Ser dipetides, Weinreb amides and N-protected proline esters), which are important intermediates, for instance, for the synthesis of proline-derived peptides, chiral reagents and catalysts for asymmetric synthesis.
