73445-27-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73445-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,4 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73445-27:
(7*7)+(6*3)+(5*4)+(4*4)+(3*5)+(2*2)+(1*7)=129
129 % 10 = 9
So 73445-27-9 is a valid CAS Registry Number.

IN VIVO ASSEMBLY OF ASGPR BINDING THERAPEUTICS

-

, (2022/02/28)

Compounds are provided that assemble together in vivo to form an ASGPR-binding compound that has an asialoglycoprotein receptor (ASGPR) binding ligand bound to an extracellular protein binding ligand for the selective degradation of the target extracellular protein in vivo to treat disorders mediated by the extracellular protein.

Simple and mild stereoselective O-glycosidation using 1,2-anhydrosugars under neutral conditions

Somasundaram, Devaraj,Balasubramanain, Kalpattu K.,Shanmugasundaram, Bhagavathy

supporting information, p. 764 - 767 (2019/02/16)

The ring opening of α-D-1,2-anhydrohexapyranoses with phenols proceeded smoothly in ethyl acetate (neutral conditions) in the absence of metal ion catalysts or additives to stereoselectively furnish 1,2-cis-α-aryl glycosides as the major product and 1,2-t

Arylboronic acid-mediated glycosylation of 1,2-dihydroxyglucoses

Izumi, Sanae,Kobayashi, Yusuke,Takemoto, Yoshiji

, p. 350 - 362 (2019/07/31)

- We explored direct dehydrative coupling of tetrahydro-2H-pyran-2,3-diol or a 1,2-dihydroxy sugar with various alcohols using a range of arylboronic acids. Among the catalysts, 2-borono-4-trifluoromethylbenzoic acid efficiently promoted acetalization of tetrahydro-2H-pyran-2,3-diol. Ferroceniumboronic acid showed the best catalytic activity for glycosylation of the 1,2-dihydroxy sugar. The major products were 1,2-cJi-a-D-glucopyranosides.

Ionic liquids as phase transfer catalysts: Enhancing the biphasic extractive epoxidation reaction for the selective synthesis of β-O-glycosides

Santiago, Cintia C.,Lafuente, Leticia,Bravo, Rodolfo,Díaz, Gisela,Ponzinibbio, Agustín

, p. 3739 - 3742 (2017/09/02)

Ionic liquids promoted the direct epoxidation of glycals acting as PTC. 1,2-anhydrosugars were prepared by the oxidation of glycals under biphasic conditions with dimethydioxirane generated in situ from oxone/acetone and amphiphilic IL's as catalysts. β-O

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.

Epoxidation of glycals with oxone-acetone-tetrabutylammonium hydrogen sulfate: A convenient access to simple β-D-glycosides and to α-D-mannosamine and D-talosamine donors

Lafont, Dominique,D'Attoma, Joseph,Gomez, Rejane,Goekjian, Peter G.

, p. 1197 - 1204 (2011/10/19)

The addition of a phase transfer catalyst during the epoxidation of perbenzylated glycals with oxone- acetone under biphasic conditions allows their complete epoxidation. The epoxides were readily transformed into methyl 1,2-trans-β-D-glycosides or 1,2-trans-β-D-glycopyranosyl azides (D-gluco and-D-galacto configurations) bearing a free hydroxyl group at the 2-position. These glycosyl azides were converted to alkyl 1,2-trans-2-acetamido- 2-deoxy-α-D-pyranosides or alkyl 2-allyloxycarbonylamino-2- deoxy-α-D-pyranosides (D-manno and D-talo configurations) by a Staudinger reaction and a double inversion of configuration at C-1 and C-2.

Tandem epoxidation-alcoholysis or epoxidation-hydrolysis of glycals catalyzed by titanium(IV) isopropoxide or Venturello's phosphotungstate complex

Levecque, Pieter,Gammon, David W.,Kinfe, Henok Hadgu,Jacobs, Pierre,De Vos, Dirk,Sels, Bert

body text, p. 1557 - 1568 (2009/07/10)

Venturello's phosphotungstate complex and titanium(IV) isopropoxide [Ti(O-i-Pr)4] were successfully used as catalysts for the epoxidation-alcoholysis of glycals using hydrogen peroxide [H2O 2]. Reaction substrates included a range of variously protected glycals and different alcohols were used as solvents. Ti(O-i-Pr)4 was only effective in methanol as solvent, but gave methyl glycosides in high yields and high selectivities. The Venturello complex proved to be a very versatile and efficient catalyst. Apart from epoxidation-alcoholysis in alcoholic solvents it also showed activity in biphasic conditions to allow for glycosylation of long-chain alcohols and was very effective in the stereoselective dihydroxylation of benzylated glucal.

Methyltrioxorhenium-catalyzed epoxidation-methanolysis of glycals under homogeneous and heterogeneous conditions

Goti, Andrea,Cardona, Francesca,Soldaini, Gianluca,Crestini, Claudia,Fiani, Cinzia,Saladino, Raffaele

, p. 476 - 486 (2007/10/03)

The efficient and high yielding domino epoxidation-methanolysis of glycals 8-15 has been achieved by oxidation with UHP in MeOH catalyzed by MTO. The products have been conveniently isolated as 2-acetoxy derivatives 16-23a, b by direct acetylation of the crude mixtures. Homogeneous MTO-amine complexes 5-7, heterogeneous poly(4-vinyl-pyridine)/MTO compounds I-III, and microencapsulated polystyrene/MTO systems IV-VII were also tested and demonstrated their effectiveness as catalysts for the oxidation step. The facial diastereoselectivity of the oxidation ranged from satisfactory to excellent depending on the substrate and could be optimized by ample screening of catalysts. Complete conversions of substrates and nearly quantitative yields of products were obtained under environmentally friendly experimental conditions and with the use of simple work-up procedures.

Cheshev, Pavel,Marra, Alberto,Dondoni, Alessandro

, p. 2714 - 2716 (2007/10/03)

A multi-gram epoxidation of 3,4,6-tri-O-benzyl-d-glucal and d-galactal with dimethyldioxirane (DMDO) generated in situ from Oxone/acetone in a biphasic system (CH2Cl2-aqueous NaHCO3) resulted in the formation of
