158478-40-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 158478-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,4,7 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 158478-40:
(8*1)+(7*5)+(6*8)+(5*4)+(4*7)+(3*8)+(2*4)+(1*0)=171
171 % 10 = 1
So 158478-40-1 is a valid CAS Registry Number.

Catalytic asymmetric synthesis of (S)-laudanosine by hydroamination

Ogata, Tokutaro,Kimachi, Tetsutaro,Yamada, Ken-Ichi,Yamamoto, Yasutomo,Tomioka, Kiyoshi

, p. 469 - 485 (2013/08/23)

Lithium amide-chiral bisoxazoline-catalyzed asymmetric intramolecular hydroamination was examined with respect to the structural variants of starting aminoalkenes. Substituents on the nitrogen and olefin of aminoalkenes were found to be important factors affecting reaction efficiency as well as enentioselectivity in the production of chiral tetrahydroisoquinolines and isoindolines. The catalytic asymmetric total synthesis of (S)-laudanosine highlights the utility of the asymmetric hydroamination.

Synthesis of pyrrolizidines using aminyl radicals generated from sulfenamide precursors

Russell Bowman,Clark, David N.,Marmon, Robert J.

, p. 1295 - 1310 (2007/10/02)

Tandem radical cyclisations of aminyl radicals generated from sulfenamide precursors have been used for the synthesis of pyrrolizidines and other polycyclic nitrogen heterocycles. The aminyl radicals are generated by reaction between sulfenamide precursor
