22686-81-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22686-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,6,8 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22686-81:
(7*2)+(6*2)+(5*6)+(4*8)+(3*6)+(2*8)+(1*1)=123
123 % 10 = 3
So 22686-81-3 is a valid CAS Registry Number.

Access to 2-Arylquinazolin-4(3H)-ones through Intramolecular Oxidative C(sp3)?H/N?H Cross-Coupling Mediated by I2/DMSO

Wen, Simiaomiao,Du, Yifan,Liu, Yiwen,Cui, Xiaofeng,Liu, Qixing,Zhou, Haifeng

, (2021/12/01)

A novel approach for the synthesis of 2-arylquinazolin-4(3H)-ones was developed. A series of title compounds were obtained with good functional group tolerance and good yields by I2/DMSO-mediated intramolecular oxidative cross-coupling of 2-(benzylamino)benzamides to form C=N double bonds. This method was applicable for gram-scale synthesis. A proposed reaction pathway based on some control experiments was also provided.

An efficient transition-metal-free route to quinazolin-4(3H)-onesvia2-aminobenzamides and thiols

supporting information, p. 15344 - 15349 (2021/09/07)

An efficient approach to quinazolin-4(3H)-ones was developed by a one-pot intermolecular annulation reaction ofo-amino benzamides and thiols. This method has the features of good functional group tolerance, being transition metal and external oxidant free, and easy operation. Varieties of 2-aryl (heteroaryl) quinazolin-4(3H)-one, 2-phenyl-pyrido[2,3-d]pyrimidin-4(3H)-one and 3-phenyl-2H-1,2,4-benzo thiadiazine-1,1-dioxide derivatives were obtained with a yield of up to 98%. The control experiment revealed that the thiol substrate could promote the dehydroaromatization step.

Metal-free catalyst for the visible-light-induced photocatalytic synthesis of quinazolinones

Wang, Rongzhou,Liu, Shiyuan,Li, Longfei,Song, Ao,Yu, Shengsheng,Zhuo, Shuping,Xing, Ling-Bao

, (2021/07/07)

In the present work, we have developed a novel and environmentally friendly method for the synthesis of quinazolinones using fluorescein as a photocatalyst via a condensation reaction of o-aminobenzamides and aldehydes under visible light irradiation. In this protocol, neither toxic oxidants nor transition-metal catalysts were needed, and a series of quinazolinones could be obtained in high efficiencies. In addition, this reaction can be extended to gram levels and has a large potential of wide application in future industrialization.
