36041-80-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 36041-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,0,4 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 36041-80:
(7*3)+(6*6)+(5*0)+(4*4)+(3*1)+(2*8)+(1*0)=92
92 % 10 = 2
So 36041-80-2 is a valid CAS Registry Number.

Application of axially dissymmetric ligand recoverable with fluorous solvent as a chiral auxiliary

Omote, Masaaki,Nishimura, Yuji,Sato, Kazuyuki,Ando, Akira,Kumadaki, Itsumaro

, p. 74 - 78 (2006)

(Ra)-(R)2-2,2′-Bis(1-hydroxy-1H-perfluorooctyl)biphenyl ((Ra)-(R)2-1c), which is an axially dissymmetric ligand with two chiral centers, works as a good chiral auxiliary for asymmetric aldol reaction. Thus, the reaction of monopropan

Fe-Catalyzed Anaerobic Mukaiyama-Type Hydration of Alkenes using Nitroarenes

Bhunia, Anup,Bergander, Klaus,Daniliuc, Constantin Gabriel,Studer, Armido

supporting information, p. 8313 - 8320 (2021/03/08)

Hydration of alkenes using first row transition metals (Fe, Co, Mn) under oxygen atmosphere (Mukaiyama-type hydration) is highly practical for alkene functionalization in complex synthesis. Different hydration protocols have been developed, however, control of the stereoselectivity remains a challenge. Herein, highly diastereoselective Fe-catalyzed anaerobic Markovnikov-selective hydration of alkenes using nitroarenes as oxygenation reagents is reported. The nitro moiety is not well explored in radical chemistry and nitroarenes are known to suppress free radical processes. Our findings show the potential of cheap nitroarenes as oxygen donors in radical transformations. Secondary and tertiary alcohols were prepared with excellent Markovnikov-selectivity. The method features large functional group tolerance and is also applicable for late-stage chemical functionalization. The anaerobic protocol outperforms existing hydration methodology in terms of reaction efficiency and selectivity.

Manganese-Catalyzed anti-Selective Asymmetric Hydrogenation of α-Substituted β-Ketoamides

Ding, Kuiling,Han, Zhaobin,Wang, Zheng,Zhang, Linli

supporting information, p. 15565 - 15569 (2020/07/06)

A Mn-catalyzed diastereo- and enantioselective hydrogenation of α-substituted β-ketoamides has been realized for the first time under dynamic kinetic resolution conditions. anti-α-Substituted β-hydroxy amides, which are useful building blocks for the synthesis of bioactive molecules and chiral drugs, were prepared in high yields with excellent selectivity (up to >99 percent dr and >99 percent ee) and unprecedentedly high activity (TON up to 10000). The origin of the excellent stereoselectivity was clarified by DFT calculations.
