58686-70-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 58686-70-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,6,8 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 58686-70:
(7*5)+(6*8)+(5*6)+(4*8)+(3*6)+(2*7)+(1*0)=177
177 % 10 = 7
So 58686-70-7 is a valid CAS Registry Number.

Efficient Access to Chiral β-Borylated Carboxylic Esters via Rh-Catalyzed Hydrogenation

Liu, Gang,Li, Anqi,Qin, Xueyuan,Han, Zhengyu,Dong, Xiu-Qin,Zhang, Xumu

, p. 2844 - 2848 (2019/04/26)

Rh/bisphosphine?thiourea ligand (ZhaoPhos)-catalyzed asymmetric hydrogenation of (Z)-β-substituted-β-boryl-α,β-unsaturated esters was successfully developed, furnishing a variety of chiral β-borylated carboxylic esters with high yields and excellent enantioselectivities (up to 99% yield and >99% ee). The gram-scale asymmetric hydrogenation was performed efficiently in the presence of only 0.05 mol% (S/C=2 000) catalyst loading with full conversion, 99% yield and 99% ee. Moreover, the hydrogenation product was easily converted to other versatile synthetic intermediates, such as methyl (S)-3-hydroxy-3-phenylpropanoate and methyl (S)-3-(furan-2-yl)-3-phenylpropanoate. (Figure presented.).

Palladium-Catalyzed Regio- and Stereoselective Sulfonylation of Aryl Propiolates with Sulfonyl Hydrazides: Access to (E)-β-Aryl Sulfonyl Acrylates

Jiang, Huanfeng,Yan, Wuxin,Huang, Jiuzhong,Tan, Chaowei,Zhan, Lingzhi,Wu, Wanqing

supporting information, p. 4575 - 4580 (2019/09/16)

An efficient method for the synthesis of (E)-β-aryl sulfonyl acrylates has been reported. This palladium-catalyzed approach showed excellent regio- and stereoselectivity in the sulfonylation of aryl propiolates with sulfonyl hydrazides. Through this approach, a wide range of (E)-β-aryl sulfonyl acrylates were obtained in moderate to high yields. (Figure presented.).

Rhodium-catalyzed C(sp2)-H addition of arylboronic acids to alkynes using a boron-based, convertible ortho-directing group

Yamamoto, Takeshi,Ishibashi, Aoi,Suginome, Michinori

, p. 1169 - 1172 (2017/08/07)

Temporary modification of a boronyl group with pyrazoryl-aniline allowed insertion of arylpropiolates and diphenylacet-ylenes into the o-C-H bond of arylboronic acids in the presence of rhodium catalysts, giving 3,3-diarylacrylates and triarylethene conta
