66893-75-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66893-75-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,8,9 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66893-75:
(7*6)+(6*6)+(5*8)+(4*9)+(3*3)+(2*7)+(1*5)=182
182 % 10 = 2
So 66893-75-2 is a valid CAS Registry Number.

Fragment-oriented synthesis: β-elaboration of cyclic amine fragments using enecarbamates as platform intermediates

Trindade, Alexandre F.,Faulkner, Emily L.,Leach, Andrew G.,Nelson, Adam,Marsden, Stephen P.

supporting information, p. 8802 - 8805 (2020/08/17)

A strategy for the β-sp3 functionalisation of cyclic amines is described. Regioselective conversion of protected amines to enecarbamates is achieved through electrochemical oxidation; these intermediates can be derivatised by functionalised alkyl halides under photoredox catalysis. The potential of the methods is highlighted by direct growth of a DCP2B-binding fragment. This journal is

Diastereoselective synthesis of 3-fluoro-2-substituted piperidines and pyrrolidines

Gichuhi, Paul N.,Kuriyama, Masami,Onomura, Osamu

, p. 331 - 346 (2014/01/17)

A facile procedure for synthesis of trans-3-fluoro-2-substituted piperidines by utilizing electrophilic fluorination of cyclic enamines and Lewis acid mediated nucleophilic substitution has been developed. Also, optically active trans-2-allyl-3-fluorinate

Stereoselective synthesis of 3-deoxy-piperidine iminosugars from l-lysine

Moriyama, Noriaki,Matsumura, Yoshihiro,Kuriyama, Masami,Onomura, Osamu

scheme or table, p. 2677 - 2687 (2010/04/29)

A new method using electrochemical oxidation and/or OsO4 oxidation has been used for the stereoselective synthesis of 2,3,6-trihydroxylated (5S)-piperidine derivatives. The electrochemical method was successively used for the conversion of N-pr
