466-96-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 466-96-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 466-96:
86 % 10 = 6
So 466-96-6 is a valid CAS Registry Number.

A total synthesis of (±)-codeine by 1,3-dipolar cycloaddition

Erhard, Thomas,Ehrlich, Gunnar,Metz, Peter

, p. 3892 - 3894 (2011/06/24)

Nitrone cycloaddition on a dearomatized bicyclic phenol enabled the facile construction of the correctly configured phenanthrene skeleton of codeine. Further steps yielded allopseudocodeine in a completely diastereoselective manner and finally (±)-codeine by allylic transposition through the hydrolysis of chlorocodides.

Claisen Reactions on Codeins. 8-Alkyl-8,14-dihydro-6-demethoxythebaines and -oripavines

Fleischhacker, Wilhelm,Richter, Bernd

, p. 3866 - 3880 (2007/10/02)

Claisen Eschenmoser reaction of 1a leads to 2a, which is transformed to 2c, e, and f by especially adopted reduction conditions.Reduction of 2i with LiAlH4 gives 2g.Catalytic hydrogenation of 2 results in ether bridge opening and formation of 4.Reaction of 2e with 4 N HCl yields the cyclic phenol 7a.Orthoester Claisen rearrangement of 1a leads to orthoacetate 10 and 11.Claisen Eschenmoser reaction on codeine isomers 1b and 12c gives the amides 12a and 1f.
