58341-67-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 58341-67-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,3,4 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 58341-67:
(7*5)+(6*8)+(5*3)+(4*4)+(3*1)+(2*6)+(1*7)=136
136 % 10 = 6
So 58341-67-6 is a valid CAS Registry Number.

Co2(CO)6-propargyl cation mediates glycosylation reaction by using thioglycoside

Xia, Meng-jie,Yao, Wang,Meng, Xiang-bao,Lou, Qing-hua,Li, Zhong-jun

supporting information, p. 2389 - 2392 (2017/05/29)

We discovered that the cobalt-propargyl cation can mediate the glycosylation reaction by activating the thioglycoside donor. The glyco-oxacarbenium cation was formed by transferring the thio-aglycone to the cobalt-propargyl cation that was generated from the cobalt-propargylated acceptor in situ via the activating with Lewis acid. The reactivity of the donor (Armed or dis-armed) and the amount of the Lewis acid control the releasing rate of the cobalt-propargyl group.

Nucleofuge Generating Glycosidations by the Remote Activation of Hydroxybenzotriazolyl Glycosides

Neralkar, Mahesh,Mishra, Bijoyananda,Hotha, Srinivas

, p. 11494 - 11504 (2017/11/10)

Hydroxybenzotriazole is routinely used in peptide chemistry for reducing racemization due to the increased reactivity. In this article, very stable hydroxybenzotriazolyl glucosides were identified to undergo glycosidation. The reaction was hypothesized to go through the remote activation by the Tf2O at the N3-site of HOBt followed by the extrusion of the oxocarbenium ion that was attacked by the glycosyl acceptor. Further, equilibration of the zwitterionic benzotriazolyl species makes the leaving group noncompetitive and generates the nucleofuge that has been reconverted to the glycosyl donor. The reaction is mild, high yielding, fast and suitable for donors containing both C2-ethers and C2-esters as well. The regenerative-donor glycosidation strategy is promising as it enables us to regenerate the glycosyl donor for further utilization. The utility of the methodology for the oligosaccharide synthesis was demonstrated by the successful synthesis of the branched pentamannan core of the HIV1-gp120 complex.

Four Different Regioisomeric Polycarbonates Derived from One Natural Product, d -Glucose

Lonnecker, Alexander T.,Lim, Young H.,Felder, Simcha E.,Besset, Céline J.,Wooley, Karen L.

, p. 7857 - 7867 (2016/11/09)

Strategies for the preparation of polycarbonates, derived from the natural product d-glucose, which have the potential to degrade back into their bioresorbable starting material and CO2, were developed. By employing established carbohydrate pro

Gold-catalysed glycosylation reaction using an easily accessible leaving group

Koppolu, Srinivasa Rao,Niddana, Ramana,Balamurugan, Rengarajan

supporting information, p. 5094 - 5097 (2015/05/13)

Gold(iii)-catalysed glycosylation reaction has been developed by employing a new and easily accessible leaving group synthesized from ethyl cyanoacetate. Several nucleophiles like alcohols, thiols, allyltrimethylsilane, trimethylsilyl azide and triethylsilane have been reacted to make the corresponding glycosides in good yields and with marginal to excellent α-selectivity.

β-Rhamnosides from 6-thio mannosides

Christina, Alphert E.,Es, Daan Van Der,Dinkelaar, Jasper,Overkleeft, Hermen S.,Marel, Gijsbert A. Van Der,Codee, Jeroen D. C.

, p. 2686 - 2688 (2012/04/10)

Upon condensation of 6-thio-6-deoxy-mannosyl donors 1,2-cis products are obtained with a high degree of stereoselectivity. Subsequent reductive removal of the 6-thio functionality gives 1,2-cis rhamnosides. The 1,2-cis-selectivity can be rationalized with

Some observations on the reductive ring opening of 4,6-O-benzylidene acetals of hexopyranosides with the borane trimethylamine-aluminium chloride reagent

Daragics, Katalin,Szabó, Pál,Fügedi, Péter

experimental part, p. 1633 - 1637 (2011/09/14)

Reductive ring openings of 3-O-benzoyl-4,6-O-benzylidene-d-glucopyranosides with BH3·NMe3-AlCl3 are accompanied by side reactions, such as debenzoylation and reduction of the benzoate to benzyl ether. This phenomenon was r

Rapid assembly of gp120 oligosaccharide moieties via one-pot glycosidation-deprotection sequences

Mannosyl trihaloacetimidate donors equipped with a 2-O-Fmoc group can be effectively activated by catalytic Bi(OTf)3 in glycosidations. Despite the expected participating effect of the Fmoc group, the reaction solvent was found to be decisive f

One-pot catalytic glycosidation/Fmoc removal - An iterable sequence for straightforward assembly of oligosaccharides related to HIV gp120

Pastore, Antonello,Adinolfi, Matteo,Iadonisi, Alfonso,Valerio, Silvia

experimental part, p. 711 - 718 (2010/03/24)

The removal of a transient Fmoc protecting group can be simply performed by the addition of excess Et3N just after the accomplishment of a Bi(OTf)3-promoted glycosidation reaction. The obtained oligosaccharide can be directly employed as a glycosyl acceptor for further elongation of the saccharide. The preparation of biologically important, linear and branched mannans incorporated into HIV gp 120 demonstrates that the iteration of this one-pot sequence leads to a very straightforward oligosaccharide assembly.
