3-[(4-methylphenyl)sulfonyl]quinazolin-4(3H)-one is a complex organic chemical compound with the molecular formula C16H13N2O3S. It is a derivative of quinazolinone, a heterocyclic compound with potential applications in medicinal chemistry, particularly as a building block for the synthesis of various bioactive molecules. The compound features a quinazolinone core, with a sulfonyl group attached to the 3-position and a 4-methylphenyl group at the sulfonyl moiety. This specific structure may contribute to its potential biological activities, such as inhibiting certain enzymes or interacting with specific receptors, although further research would be needed to confirm its exact properties and applications.

5465-78-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5465-78-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,6 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5465-78:
(6*5)+(5*4)+(4*6)+(3*5)+(2*7)+(1*8)=111
111 % 10 = 1
So 5465-78-1 is a valid CAS Registry Number.

Regioselective sulfonylation and N- to O-sulfonyl migration of quinazolin-4(3H)-ones and analogous thienopyrimidin-4(3H)-ones

Mertens, Matthias D.,Pietsch, Markus,Schnakenburg, Gregor,Guetschow, Michael

, p. 8966 - 8979 (2013/10/08)

The sulfonylation of quinazolin-4(3H)-ones and related tetrahydrobenzothieno[2,3-d]pyrimidin-4(3H)-ones with mesyl, tosyl, and p-cyanobenzenesulfonyl chloride was studied. A hydrogen substituent at 2-position directed the sulfonyl group to the N-3 position, while alkylsulfanyl or amino substituents led to sulfonylation of the carbonyl oxygen. The latter effect was attributed to steric influence and the positive mesomeric effect of the 2-substituent. An access to N-sulfonylated 2-substituted regioisomers was established. An unexpected 1,3-sulfonyl migration was observed and further analyzed. This process occurred as an intramolecular N- to O-shift as verified by kinetic and crossover experiments.
