89764-36-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89764-36-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,6 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 89764-36:
(7*8)+(6*9)+(5*7)+(4*6)+(3*4)+(2*3)+(1*6)=193
193 % 10 = 3
So 89764-36-3 is a valid CAS Registry Number.

The Asymmetric Diels-Alder Cycloaddition Using Ethyl(-)-(Z)-(R)s-2-methyl-3-(p-tlylsulfinyl)propenoate: Application to an Enantioselective Synthesis of (+)-epi-β-Santalene

Arai, Yoshitsugu,Yamamoto, Masatoshi,Koizumi, Toru

, p. 467 - 474 (2007/10/02)

The Diels-Alder reaction of ethyl (-)-(Z)-(R)s-2-methyl-3-(p-tolylsulfinyl)propenoate (6) with cyclopentadiene gave the adducts, 7, 8, and 9 in a high diastereoselective manner.The cycloadduct 7 was transformed into the acetal (-)-25.The racemic 25 was used as an intermediate in the synthesis of (+/-)-β-santalol.Thus, the chiral acetal (-)-25 should provide a route to (-)-Β-santalol.The cycloadduct 8 was converted into (+)-epi-β-santalene in 11 steps.

HIGHLY DIASTEREOSELECTIVE DIELS-ALDER REACTION OF OPTICALLY ACTIVE ETHYL 2-p-TOLYLSULFINYLMETHYLENEPROPIONATE WITH CYCLOPENTADIENE

Koizumi, Toru,Hakamada, Ichiro,Yoshii, Eiichi

, p. 87 - 90 (2007/10/02)

Stereochemistry of the Diels-Alder reaction of ethyl Z- and E-2-p-tolylsulfinylmethylenepropionate with cyclopentadiene has been studied.The high diastereoselectivity was observed especially in the case of exo-cycloaddition.
