4560-13-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4560-13-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,6 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4560-13:
(6*4)+(5*5)+(4*6)+(3*0)+(2*1)+(1*3)=78
78 % 10 = 8
So 4560-13-8 is a valid CAS Registry Number.

Pd(II)-Catalyzed Intramolecular C(sp2)-H Arylation of Tryptamines Using the Nonsteric NH2as a Directing Group

Wang, Sixi,Yu, Bin,Liu, Hong-Min

supporting information, p. 42 - 48 (2021/01/09)

The free amine-directed C-H functionalization reactions are challenging and mainly restricted to bulky amines. In this work, we report the nonsteric NH2-directed Pd(II)-catalyzed intramolecular C(sp2)-H arylation of tryptamines, which enables the efficient, gram-scale, and regioselective synthesis of versatile 2-aryltryptamines (35 examples, up to 98% yield). This approach broadens the substrate scope of the free amine-directed C-H functionalization, not limited to bulky amine substrates. Late-stage elaborations of 2-aryltryptamines achieve the divergent construction of the complex core structures that are prevalent in highly valuable natural products such as aurantioclavine, chimonanthine, and phalarine.

A versatile linkage strategy for solid-phase synthesis of N,N-dimethyltryptamines and β-carbolines

Wu, Tom Y. H.,Schulte, Peter G.

, p. 4033 - 4035 (2007/10/03)

(matrix presented) Various tryptamines are captured by a vinylsulfonylmethyl polystyrene resin, generating a safety-catch linkage. β-Carbolines can be formed from 4 by a Pictet-Spengler reaction with the introduction of R1. Tryptamine 4 can also be derivatized by acylation or copper-mediated coupling to introduce R2. If X = Br, Suzuki coupling can be used to introduce R3. After derivatization, the indole derivatives are activated with methyl iodide and released under mild basic condition.
