211758-35-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 211758-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,7,5 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 211758-35:
(8*2)+(7*1)+(6*1)+(5*7)+(4*5)+(3*8)+(2*3)+(1*5)=119
119 % 10 = 9
So 211758-35-9 is a valid CAS Registry Number.

Highly diastereoselective Diels-Alder reactions of acrylic esters incorporated into a variety of hexopyranosides

Nagatsuka, Takayuki,Yamaguchi, Shuhei,Totani, Kiichiro,Takao, Ken-ichi,Tadano, Kin-ichi

, p. 519 - 535 (2007/10/03)

The Diels-Alder reactions of a variety of hexopyranosides carrying an acrylic ester with cyclopentadiene were examined. Some acrylic esters provided the cycloaddition products carrying a norbornene carboxylate with a high level of diastereoselectivity. Plausible mechanisms are presented for the cases of a 4-O-acryloyl-6-deoxy-α-D-glucopyranosidic and 2-O-acryloyl-α-D-glucopyranosidic substrates. By reductive removal of the carbohydrate templates from the adducts, either 2S or 2R-enriched 5-norbornene-2-methanol were obtained.

Novel application of chiral micellar media to the Diels-Alder reaction

Diego-Castro, Michael J.,Hailes, Helen C.

, p. 1549 - 1550 (2007/10/03)

A novel chiral surfactant has been used in the first reported aqueous chiral micellar catalysis of a Diels-Alder reaction and enantioselectivities have been observed.
