3969-02-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3969-02-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,6 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3969-02:
(6*3)+(5*9)+(4*6)+(3*9)+(2*0)+(1*2)=116
116 % 10 = 6
So 3969-02-6 is a valid CAS Registry Number.

Oxidation of didehydro-α-amino acids as a route to β-hydroxy-or β-amino-pyruvic derivatives and to α-acylglycinates

Miossec, Benoit,Rudyk, Helene,Toupet, Loic,Danion-Bougot, Renee,Danion, Daniel

, p. 1833 - 1837 (1996)

Oxidation of protected didehydro-α-amino acids with N-bromosuccinimide or lead tetraacetate affords imines of β-bromo- or β-acetoxy-pyruvates. The hydrolysis of brominated imines proceeds through addition of water followed by intramolecular displacement o

Synthesis of 2-oxazolone-4-carboxylates from 3-nosyloxy- and 3-bromo-2-ketoesters

Okonya, John F.,Hoffman, Robert V.,Johnson, M. Catherine

, p. 1102 - 1108 (2007/10/03)

New methods for the synthesis of 2-oxazolone-4-carboxylates from 3-nosyloxy- and 3-bromo-2-ketoesters are described. Condensation of 3-nosyloxy-2-ketoesters with methyl carbamate in refluxing toluene in the presence of p-TSA provided 2-oxazolone-4-carboxylates in good yields (41-80%). Alternatively, bromination of α-ketoesters with CuBr2 provided 3-bromo-2-ketoesters which condensed with methyl carbamate in the presence of p-TSA and AgOTfunder similar conditions to provide 2-oxazolone-4-carboxylates in comparable yields (30-79%). The 2-oxazolone-4-carboxylates bear functionality that can be elaborated to a variety of potentially useful compounds. For example, some of these heterocycles were readily N-acylated, reduced to alcohols, or saponified and coupled with amino acids.

Synthesis of 4-carboethoxy-4-oxazolin-2-ones from 3-nosyloxy-2-ketoesters

Hoffman, Robert V.,Johnson, M. Catherine,Okonya, John F.

, p. 1283 - 1286 (2007/10/03)

3-Nosyloxy-2-ketoesters, available from 2-ketoesters, react efficiently with methyl carbamate and tosic acid in refluxing toluene to provide 4-carboalkoxy-4-oxazolin-2-ones in good yields (41-84%).
