312920-40-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 312920-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,2,9,2 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 312920-40:
(8*3)+(7*1)+(6*2)+(5*9)+(4*2)+(3*0)+(2*4)+(1*0)=104
104 % 10 = 4
So 312920-40-4 is a valid CAS Registry Number.

Divergent enantioselective synthesis of (-)-galanthamine and (-)-morphine

Trost, Barry M.,Tang, Weiping,Toste, F. Dean

, p. 14785 - 14803 (2007/10/03)

An efficient divergent synthetic strategy for the synthesis of the opiate and amaryllidaceae alkaloids emerges by employing a Pd-catalyzed asymmetric allylic alkylation (AAA) to set the stereochemistry. Three generations of syntheses of galanthamine are discussed in detail with particular focus on the scope of the palladium-catalyzed AAA reactions and intramolecular Heck reactions. The pivotal tricyclic intermediate is available in six steps from 2-bromovanillin and the monoester of methyl 6-hydroxycyclohexene-1-carboxylate. This intermediate requires only two steps to convert to (-)-galanthamine. Using a Heck vinylation, we found that the fourth ring of codeine/morphine could be formed. The final ring formation involves a novel visible light-promoted hydroamination. Thus, six steps are required to convert the pivotal tricyclic intermediate into codeine, which has been demethylated in high yield to morphine.
