142053-20-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 142053-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,5 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142053-20:
(8*1)+(7*4)+(6*2)+(5*0)+(4*5)+(3*3)+(2*2)+(1*0)=81
81 % 10 = 1
So 142053-20-1 is a valid CAS Registry Number.

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

Keusenkothen,Smith

, p. 2977 - 2992 (2007/10/02)

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.

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
