52031-69-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52031-69-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,3 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52031-69:
(7*5)+(6*2)+(5*0)+(4*3)+(3*1)+(2*6)+(1*9)=83
83 % 10 = 3
So 52031-69-3 is a valid CAS Registry Number.

Practical access to fluorescent 2,3-naphthalimide derivatives: Via didehydro-Diels-Alder reaction

Chen, Xia,Zhong, Cheng,Lu, Yuling,Yao, Meng,Guan, Zhenhua,Chen, Chunmei,Zhu, Hucheng,Luo, Zengwei,Zhang, Yonghui

supporting information, p. 5155 - 5158 (2021/05/31)

A practical and efficient approach for the synthesis of fluorescent 2,3-naphthalimide derivatives has been developed from readily available starting materials via an intramolecular didehydro-Diels-Alder reaction, which proceeded well under room temperature, exhibiting a wide substrate scope and good functional group tolerance. The practicability of this methodology has been verified by one-step synthesis of the environmentally sensitive fluorophore 6-DMN on a gram scale with a shorter time, fewer steps and less waste disposal, and without the utilization of toxic transition metals. The present experimental and computational studies support the crucial role of the propiolimide moiety in the transformation.

Modular Cyclopentenone Synthesis through the Catalytic Molecular Shuffling of Unsaturated Acid Chlorides and Alkynes

Lee, Yong Ho,Denton, Elliott H.,Morandi, Bill

supporting information, p. 20948 - 20955 (2020/12/21)

We describe a general strategy for the intermolecular synthesis of polysubstituted cyclopentenones using palladium catalysis. Overall, this reaction is achieved via a molecular shuffling process involving an alkyne, an α,β-unsaturated acid chloride, which serves as both the alkene and carbon monoxide source, and a hydrosilane to create three new C-C bonds. This new carbon monoxide-free pathway delivers the products with excellent yields. Furthermore, the regioselectivity is complementary to conventional methods for cyclopentenone synthesis. In addition, a set of regio- and chemodivergent reactions are presented to emphasize the synthetic potential of this novel strategy.

Concise Synthesis of Natural Phenylphenalenone Phytoalexins and a Regioisomer

Wang, Ming-Zhong,Ku, Chuen-Fai,Si, Tong-Xu,Tsang, Siu-Wai,Lv, Xiao-Meng,Li, Xiao-Wan,Li, Zheng-Ming,Zhang, Hong-Jie,Chan, Albert S. C.

, p. 98 - 105 (2018/02/07)

Concise total syntheses of the natural phytoalexins 2-hydroxy-8-(4-hydroxyphenyl)phenalen-1-one (1), 2-hydroxy-8-(3,4-dihydroxyphenyl)phenalen-1-one (2), and hydroxyanigorufone (4), together with regioisomer 3 are accomplished in 11 or 12 steps. The synthetic strategy features a Friedel-Crafts acylation to construct the 1H-phenalen-1-one tricyclic core followed by a Suzuki cross-coupling to obtain the target compounds.
