126908-53-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 126908-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,9,0 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 126908-53:
(8*1)+(7*2)+(6*6)+(5*9)+(4*0)+(3*8)+(2*5)+(1*3)=140
140 % 10 = 0
So 126908-53-0 is a valid CAS Registry Number.

Asymmetric radical cyclizations: The synthesis of 6-alkyl pyrrolizidin-2-ones

Keusenkothen,Smith

, p. 2977 - 2992 (1992)

This work describes the use of ethyl (5S)-carboethoxy-2-pyrrolidinone (ethyl pyroglutamate) as a chiral starting material for use in radical cyclization reactions. Pyroglutamate is converted to a 5-iodomethyl-N-allylic-2-pyrrolidinone that undergoes radical cyclization under mild conditions. The products are 6-substituted pyrrolizidinone derivatives, produced with high diastereoselectivity.

AN IMPROVED REDUCTION OF THE ESTER MOIETY IN N-SUBSTITUTED PYROGLUTAMATES

Keusenkothen, Paul F.,Smith, Michael B.

, p. 2859 - 2868 (2007/10/02)

Lithium borohydride reduction of N-functionalized pyroglutamates failed to give the corresponding hydroxymethyl derivative.Reduction with lithium aluminium hydride bound to dry silica gel, however, gace excellent yields of chiral 5-hydroxymethyl-1-allyl-2

ASYMMETRIC SYNTHESIS OF PYRROLIZIDINONES BY RADICAL CYCLIZATION OF N-ALLYLIC PYROGLUTAMATES

Keusenkothen, Paul F.,Smith, Michael B.

, p. 3369 - 3372 (2007/10/02)

Ethyl S-pyroglutamate is converted to N-allylic-S C5-iodomethyl-2-pyrrolidinone.Facile radical cyclization on treatment with AIBN and tributyltin hydride in refluxing benzene gives good yields of the C6 substituted pyrrolizidin-2-one
