Yellow crystalline powder

Check Digit Verification of cas no

The CAS Registry Mumber 39745-39-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,7,4 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39745-39:
156 % 10 = 6
So 39745-39-6 is a valid CAS Registry Number.

Phenacylation of 6-methyl-beta-nitropyridin-2-ones and further heterocyclization of products

Babaev, Eugene V.,Rybakov, Victor B.

, (2020/04/17)

Reaction between the derivatives of 6-methyl-beta-nitropyridin-2-one and phenacyl bromides was studied, and the yields observed were extremely low. The pyridones were converted via chloropyridines to methoxyderivatives, which were N-phenacylated. N-Phenacyl derivatives of 4,6-dimethyl-5-nitropyridin-2-one under the action of base gave 5-hydroxy-8-nitroindolizine and under acidic conditions gave 5-methyl-6-nitrooxazole[3,2-a]pyridinium salt, which underwent recycization with MeONa to 5-methoxy-8-nitroindolizine.

Synthetic equivalent of α-nitroformylacetic acid

, p. 1581 - 1590 (2007/10/03)

A novel synthetic procedure for 3-nitro-2-pyridone derivatives (2) is provided, which includes the ring transformation of 1,3-dinitroquinolizin-4-one (3) with ketones in the presence of ammonium acetate.

Versatile synthesis of 6-substituted 8-deazapteridine-2,4-diamines. Formal total synthesis of 8,10-dideazaminopterin


, p. 1815 - 1821 (2007/10/03)

A new synthesis of 4-amino-4-deoxy-8,10-dideazapteroic acid (11d) and 6-substituted and 5,6-anellated 8-deazapteridine-2,4-diamines, 10a, 10d, 25, is described. Starting from keteneaminals 1 or 12 and enaminones 4 or β-aminoketone 17 the title compounds can be prepared via functional group transformation of 2-amino-3-nitropyridines 5 or nicotinate 13a yielding 3-amino-α-picolinonitriles 9 which are cyclocondensed with guanidine.
