1859-00-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1859-00-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,5 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1859-00:
(6*1)+(5*8)+(4*5)+(3*9)+(2*0)+(1*0)=93
93 % 10 = 3
So 1859-00-3 is a valid CAS Registry Number.

Photoredox synthesis of functionalized quinazolinesviacopper-catalyzed aerobic oxidative Csp2-H annulation of amidines with terminal alkynes

Charpe, Vaibhav Pramod,Hwang, Kuo Chu,Ragupathi, Ayyakkannu,Sagadevan, Arunachalam

supporting information, p. 5024 - 5030 (2021/07/29)

We have developed a visible light-induced photo-redox copper-catalyzed oxidative Csp2-H annulation (Friedel-Crafts-type cyclization) of amidines with terminal alkynes at room temperature to synthesize functionalized quinazolines. We report copp

Synthesis of aminoisoquinolines via Rh-catalyzed [4 + 2] annulation of benzamidamides with vinylene carbonate

Huang, Xin,Xu, Yingying,Li, Jianglian,Lai, Ruizhi,Luo, Yi,Wang, Qiantao,Yang, Zhongzhen,Wu, Yong

supporting information, p. 3518 - 3521 (2021/06/12)

A new strategy is developed for the synthesis of 1-aminoisoquinoline derivatives. This Rh(III)-catalyzed [4 + 2] annulation reaction employs benzamidines as efficient directing groups and the vinylene carbonate as an acetylene surrogate. Additionally, the reaction features broad substrate scopes and good yields, only producing carbonate anion as byproduct.

Practical Synthesis of Benzimidazo[1,2- A[quinolines via Rh(III)-Catalyzed C-H Activation Cascade Reaction from Imidamides and Anthranils

Hu, Yao,Wang, Ting,Liu, Yanzhao,Nie, Ruifang,Yang, Ninghong,Wang, Qiantao,Li, Guo-Bo,Wu, Yong

supporting information, p. 501 - 504 (2020/01/31)

We report a novel and practical one-pot Rh(III)-catalyzed strategy to construct benzimidazo[1,2-a]quinolines from readily available imidamides and anthranils. The cascade reaction proceeds via a C-H amination-cyclization-cyclization process in ionic liquid without any additives and possesses simple operation, moderate-to-high yield, and broad substrate scope features, which will provide the reference for the construction of biologically active fused benzimidazoles.
