1422450-71-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1422450-71-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,4,5 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1422450-71:
(9*1)+(8*4)+(7*2)+(6*2)+(5*4)+(4*5)+(3*0)+(2*7)+(1*1)=122
122 % 10 = 2
So 1422450-71-2 is a valid CAS Registry Number.

Iridium-Catalyzed Asymmetric Borylation of Unactivated Methylene C(sp3)-H Bonds

Reyes, Ronald L.,Iwai, Tomohiro,Maeda, Satoshi,Sawamura, Masaya

, p. 6817 - 6821 (2019)

Herein, we show the highly enantioselective borylation of unactivated methylene C(sp3)-H bonds in 2-alkylpyridines and 2-alkyl-1,3-azole derivatives using an iridium-BINOL-based chiral monophosphite catalyst system. Quantum chemical calculations using the artificial force induced reaction (AFIR) method suggested that a monophosphite-Ir-tris(boryl) complex generates a narrow chiral reaction pocket where the differentiation of the enantiotopic methylene C-H bonds is accomplished through an assembly of multiple noncovalent interactions.

Enantioselective Rh- or Ir-catalyzed directed C(sp3)H borylation with phosphoramidite chiral ligands

Reyes, Ronald L.,Harada, Tomoya,Taniguchi, Tohru,Monde, Kenji,Iwai, Tomohiro,Sawamura, Masaya

, p. 1747 - 1750 (2017)

Enantioselective heteroatom-directed C(sp3)H borylation reactions of 2-aminopyridines and 2-alkylpyridines with Rh- and Ir catalytic systems using commercially available chiral monophosphine ligands, respectively, were developed. This methodology provides an innovative example of a homogeneous catalytic system for C(sp3)H borylation, and allows the direct synthesis of optically active alkylboronates with a moderate level of enantioselectivity.

Synthesis of primary and secondary alkylboronates through site-selective C(sp3)-H activation with silica-supported monophosphine-Ir catalysts

Kawamorita, Soichiro,Murakami, Ryo,Iwai, Tomohiro,Sawamura, Masaya

supporting information, p. 2947 - 2950 (2013/04/10)

The site-selective activation and borylation of unactivated C(sp3)-H bonds in 2-alkylpyridines to form primary and secondary alkylboronates was achieved using silica-supported monophosphine-Ir catalysts. This borylation occurs selectively at C-H bonds located γ to the pyridine nitrogen atom. The site-selectivity of this reaction suggests that the C-H bond cleavage occurs with the assistance of a proximity effect due to N-to-Ir coordination.
