303145-32-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 303145-32-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,1,4 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 303145-32:
(8*3)+(7*0)+(6*3)+(5*1)+(4*4)+(3*5)+(2*3)+(1*2)=86
86 % 10 = 6
So 303145-32-6 is a valid CAS Registry Number.

Bi(OTf)3-Mediated (4+1) Annulation of α-Sulfonyl o-Hydroxyacetophenones with α-Hydroxy Arylketones to Access Sulfonyl 2-Aroylbenzofurans

Chang, Meng-Yang,Chen, Kuan-Ting

, p. 2594 - 2609 (2021/03/29)

In this paper, a high-yield, facile route for the scalable synthesis of sulfonyl 2-aroylbenzofurans via a Bi(OTf)3-mediated intermolecular double cyclocondensation of α-sulfonyl o-hydroxyacetophenones with substituted α-hydroxy arylketones under mild open-vessel reaction conditions is described. In the overall reaction, water is generated as the only byproduct. Various metal triflate-promoted reactions and conditions are investigated for the efficient one-pot (4+1) annulation reaction. (Figure presented.).

Rh(III)-Catalyzed and Solvent-Controlled Chemoselective Synthesis of Chalcone and Benzofuran Frameworks via Synergistic Dual Directing Groups Enabled Regioselective C-H Functionalization: A Combined Experimental and Computational Study

Yi, Wei,Chen, Weijie,Liu, Fu-Xiaomin,Zhong, Yuting,Wu, Dan,Zhou, Zhi,Gao, Hui

, p. 9508 - 9519 (2018/09/27)

By virtue of a synergistically dual-directing-group (the O-NHAc part and the hydroxyl group)-assisted strategy, the efficient and practical Rh(III)-catalyzed regioselective redox-neutral C-H functionalization of diverse N-phenoxyacetamides with propargyl alcohols has been realized, which led to the divergent synthesis of privileged benzofuran and chalcone frameworks in a solvent-controlled chemoselective manner. Experimental and computational studies reveal that the formation of the hydrogen bonding between dual directing groups and the subsequent coordination interaction between the hydroxyl group and the Rh(III) catalyst play a decisive role in promoting the regioselective migratory insertion of the alkyne moiety. Thereafter, two solvent-controlled switchable reaction pathways, which respectively involve tandem β-H elimination/hydrogen transfer/oxidative addition/C-O bond reductive elimination/oxidation (for low-polar solvents: path I-Ia via a RhIII-RhI-RhIII pathway) and oxidative addition/β-H elimination/hydrogen transfer/protonolysis (for high-polar solvents: path II-IIb via a RhIII-RhV-RhIII pathway), are followed to deliver the corresponding products with excellent chemoselectivity. Taken together, our results presented here not only give an expansion in the area of O-NHAc-directed C-H activations but also provide a rational basis for future development of synergistic dual DGs-enabled C-H functionalization reactions.

Fragmentation of 2-aroylbenzofuran derivatives by electrospray ionization tandem mass spectrometry

Dias, Herbert J.,Vieira, Tatiana M.,Crevelin, Eduardo J.,Donate, Paulo M.,Vessecchi, Ricardo,Crotti, Ant?nio E.M.

, p. 809 - 816 (2018/01/01)

We investigated the gas-phase fragmentation reactions of a series of 2-aroylbenzofuran derivatives by electrospray ionization tandem mass spectrometry (ESI-MS/MS). The most intense fragment ions were the acylium ions m/z 105 and [M+H–C6H6
