152171-13-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 152171-13-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,1,7 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 152171-13:
(8*1)+(7*5)+(6*2)+(5*1)+(4*7)+(3*1)+(2*1)+(1*3)=96
96 % 10 = 6
So 152171-13-6 is a valid CAS Registry Number.

Asymmetric Organocatalytic Synthesis of Bisindoles – Scope and Derivatizations

Retich, Christina,Br?se, Stefan

, p. 60 - 77 (2018/01/17)

Starting from 3-vinylindoles and glyoxolate imines, we created a library of diverse 4,6-bis(1H-indole-3-yl)piperidine 2-carboxylates by using 10 mol-% of a chiral phosphoric acid. Utilising electron-withdrawing groups on the starting material during the r

SN2′ boron-mediated Mitsunobu reactions - A new one-pot three-component synthesis of substituted enamides and enol benzoates

Berree, Fabienne,Gernigon, Nicolas,Hercouet, Alain,Chia, Hui Lin,Carboni, Bertrand

supporting information; experimental part, p. 329 - 333 (2009/07/04)

The conversion of (3-hydroxy-1-propen-1-yl)boronates to substituted enamides and enol benzoates is readily achieved in a one-pot procedure consisting of a regiocontrolled Mitsunobu reaction with convenient nucleophiles, followed by allylboration of aldehydes. Wiley-VCH Verlag GmbH & Co. KGaA, 2009.

Rhodium-catalyzed hydroformylation of 2-vinyl- and 3-vinyl-1-tosylpyrroles as a convenient synthetic route to the corresponding 2-(1-tosylpyrrolyl)propanals and derivatives

Settambolo, Roberta,Caiazzo, Aldo,Lazzaroni, Raffaello

, p. 4111 - 4120 (2007/10/03)

2-(1-Tosylpyrrolyl)propanals 2a-b were conveniently prepared (70% yield) via rhodium-catalyzed hydroformylation of the corresponding 2-vinyl- and 3-vinyl-1-tosylpyrroles 1a-b and successfully transformed into some new derivatives (50-90% yield).
