132589-34-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 132589-34-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,5,8 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 132589-34:
(8*1)+(7*3)+(6*2)+(5*5)+(4*8)+(3*9)+(2*3)+(1*4)=135
135 % 10 = 5
So 132589-34-5 is a valid CAS Registry Number.

Divergent Syntheses of Indoles and Quinolines Involving N1-C2-C3 Bond Formation through Two Distinct Pd Catalyses

San Jang, Su,Kim, Young Ho,Youn, So Won

supporting information, p. 9151 - 9157 (2020/11/03)

Pd-catalyzed annulative couplings of 2-alkenylanilines with aldehydes using alcohols as both the solvent and hydrogen source have been developed. These domino processes allow divergent syntheses of two significant N-heterocycles, indoles and quinolines, from the same substrate by tuning reaction parameters, which seems to invoke two distinct mechanisms. The nature of the ligand and alcoholic solvent had a profound influence on the selectivity and efficiency of these protocols. Particularly noteworthy is that indole formation was achieved by overcoming two significant challenges, regioselective hydropalladation of alkenes and subsequent reactions between the resulting Csp3-Pd species and less reactive imines.
