103702-75-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 103702-75-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,0 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 103702-75:
(8*1)+(7*0)+(6*3)+(5*7)+(4*0)+(3*2)+(2*7)+(1*5)=86
86 % 10 = 6
So 103702-75-6 is a valid CAS Registry Number.

Green glycosylation promoted by reusable biomass carbonaceous solid acid: An easy access to β-stereoselective terpene galactosides

Gorityala, Bala Kishan,Ma, Jimei,Pasunooti, Kalyan Kumar,Cai, Shuting,Liu, Xue-Wei

, p. 573 - 577 (2011)

An efficient green protocol has been developed for the atom economic glycosylation of unprotected, unactivated glycosyl donors and glycosylation of glycosyl trichloroacetimidates with the aid of reusable eco-friendly biomass carbonaceous solid acid as catalyst. The Royal Society of Chemistry.

Anomeric alkylations and acylations of unprotected mono- and disaccharides mediated by pyridoneimine in aqueous solutions

Dey, Kalyan,Jayaraman, Narayanaswamy

supporting information, p. 2224 - 2227 (2022/02/17)

A site-specific deprotonation followed by alkylations and acylations of sugar hemiacetals to the corresponding alkyl glycosides and acylated sugars in aqueous solutions is disclosed herein. Pyridoneimine as a new base is developed to mediate the deprotonation of readily available sugar hemiacetals and further reactions with alkylation and acylation agents.

Synthesis of the spirastrellolide A, B/C spiroketal: Enabling solutions for problematic au(I)-catalyzed spiroketalizations

Butler, Barry B.,Manda, Jagadeesh Nagendra,Aponick, Aaron

supporting information, p. 1902 - 1905 (2015/04/27)

A synthesis of the spirastrellolide A, B/C-ring monounsaturated spiroketal is reported. The key step relies on a Au-catalyzed spiroketalization of a propargyl triol employing an acetonide as a regioselectivity regulator. Through observation and analysis, a set of conditions has been developed that facilitates the use of a mixture of diastereomeric substrates, obviating the need to control the stereochemistry of the propargyl stereocenter and enabling a convenient retrosynthetic disconnection. The key reaction proceeds in 80% yield in 1 min at ambient temperature with the Me3PAuCl/AgOTf catalyst system. These conditions should be widely applicable for new synthetic endeavors as they appear to overcome all issues with the Au-catalyzed spiroketalization.
