Check Digit Verification of cas no

The CAS Registry Mumber 73172-56-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,1,7 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 73172-56:
(7*7)+(6*3)+(5*1)+(4*7)+(3*2)+(2*5)+(1*6)=122
122 % 10 = 2
So 73172-56-2 is a valid CAS Registry Number.

Manganese-catalyzed ring-opening carbonylation of cyclobutanol derivatives

Meyer, Tim,Yin, Zhiping,Wu, Xiao-Feng

supporting information, p. 864 - 867 (2019/02/20)

Herein, we report a manganese-catalyzed ring-opening carbonylation of cyclobutanol derivatives through cyclic C–C bond cleavage. The reaction happens via a radical-mediated pathway to selectively generate 1,5-ketoesters. A variety of substrates with subst

Stereoselective nucleophilic addition reactions to cyclic n-acyliminium ions using the indirect cation pool method: Elucidation of stereoselectivity by spectroscopic conformational analysis and dft calculations

The invention discloses a synthesis method for a 1,5-ketonic ester compound under catalyzing of inorganic base. The synthesis method comprises the following steps: taking a compound of the general formula I as a raw material, taking inorganic base as a ca

Enantioselective Photocatalytic [3 + 2] Cycloadditions of Aryl Cyclopropyl Ketones

Amador, Adrian G.,Sherbrook, Evan M.,Yoon, Tehshik P.

supporting information, p. 4722 - 4725 (2016/05/10)

Control of stereochemistry in photocycloaddition reactions remains a substantial challenge; almost all successful catalytic examples to date have involved [2 + 2] photocycloadditions of enones. We report a method for the asymmetric [3 + 2] photocycloaddition of aryl cyclopropyl ketones that enables the enantiocontrolled construction of densely substituted cyclopentane structures not synthetically accessible using other catalytic methods. These results show that the dual-catalyst strategy developed in our laboratory broadens synthetic chemists' access to classes of photochemical cycloadditions that have not previously been feasible in enantioselective form.

Sequential Michael addition/retro-Claisen condensation of aromatic β-diketones with α,β-unsaturated esters: An approach to obtain 1,5-ketoesters

Cai, Gui-Xin,Wen, Jing,Lai, Ting-Ting,Xie, Dan,Zhou, Cheng-He

supporting information, p. 2390 - 2394 (2016/03/01)

A K2CO3-catalyzed one-pot protocol involving sequential C-C bond formation and cleavage of aromatic β-diketones with α,β-unsaturated esters is developed to obtain 1,5-ketoesters. The sequential reaction via Michael addition and retro-Claisen condensation proceeds smoothly under mild conditions in up to 98% isolated yield. The mechanism study disclosed that the cascade process involved C-C bond cleavage of aromatic β-diketone as a phenacyl donor under alcoholic alkalescent conditions.

Remote ester group leads to efficient kinetic resolution of racemic aliphatic alcohols via asymmetric hydrogenation

Yang, Xiao-Hui,Wang, Ke,Zhu, Shou-Fei,Xie, Jian-Hua,Zhou, Qi-Lin

supporting information, p. 17426 - 17429 (2015/02/02)

A highly efficient method for kinetic resolution of racemic aliphatic alcohols without conversion of the hydroxyl group has been realized; the method involves hydrogenation mediated by a remote ester group and is catalyzed by a chiral iridium complex. This powerful, environmentally friendly method provides chiral δ-alkyl-δ-hydroxy esters and δ-alkyl-1,5-diols in good yields with high enantioselectivities even at extremely low catalyst loading (0.001 mol %).

Stoichiometric reactions of acylnickel(II) complexes with electrophiles and the catalytic synthesis of ketones

Wotal, Alexander C.,Ribson, Ryan D.,Weix, Daniel J.

, p. 5874 - 5881 (2015/01/09)

Acylnickel(II) complexes feature prominently in cross-electrophile coupling (XEC) reactions that form ketones, yet their reactivity has not been systematically investigated. We present here our studies on the reactivity of acylnickel(II) complexes with a series of carbon electrophiles. Bromobenzene, α-chloroethylbenzene, bromooctane, and iodooctane were reacted with (dtbbpy)NiII(C(O)C5H11)(Br) (1b) and (dtbbpy)NiII(C(O)tolyl)(Br) (1c) to form a variety of organic products. While reactions with bromobenzene formed complex mixtures of ketones, reactions with α-chloroethylbenzene were highly selective for the cross-ketone product. Reactions with iodooctane and bromooctane also produced the cross-ketone product, but in intermediate yield and selectivity. In most cases the presence or absence of a chemical reductant (zinc) had only a small effect on the selectivity of the reaction. The coupling of 1c with iodooctane (60% yield) was translated into a catalytic reaction, the carbonylative coupling of bromoarenes with primary bromoalkanes (six examples, 60% average yield).

Design and synthesis of lactam-thiophene carboxylic acids as potent hepatitis C virus polymerase inhibitors

, p. 3979 - 3985 (2014/11/08)

Herein we report the successful incorporation of a lactam as an amide replacement in the design of hepatitis C virus NS5B Site II thiophene carboxylic acid inhibitors. Optimizing potency in a replicon assay and minimizing potential risk for CYP3A4 induction led to the discovery of inhibitor 22a. This lead compound has a favorable pharmacokinetic profile in rats and dogs.

Microwave-assisted aqueous Krapcho decarboxylation

Mason, Jeremy D.,Murphree, S. Shaun

supporting information, p. 1391 - 1394 (2013/07/26)

The Krapcho decarboxylation of alkyl malonate derivatives has been adapted to aqueous microwave conditions. Various salt additives were examined, and both the cation and the anion impacted the facility of the reaction. A strong correlation was found between the pKa of the anion and the reaction rate, suggesting a straightforward base-catalyzed hydrolysis. Lithium sulfate gave the best results, obviating the need for DMSO co-solvent. Georg Thieme Verlag Stuttgart · New York.
