862907-25-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 862907-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,9,0 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 862907-25:
(8*8)+(7*6)+(6*2)+(5*9)+(4*0)+(3*7)+(2*2)+(1*5)=193
193 % 10 = 3
So 862907-25-3 is a valid CAS Registry Number.

Electrochemical Umpolung C-H Functionalization of Oxindoles

Pastor, Miryam,Vayer, Marie,Weinstabl, Harald,Maulide, Nuno

, p. 606 - 612 (2022/01/12)

Herein, we present a general electrochemical method to access unsymmetrical 3,3-disubstituted oxindoles by direct C-H functionalization where the oxindole fragment behaves as an electrophile. This Umpolung approach does not rely on stoichiometric oxidants and proceeds under mild, environmentally benign conditions. Importantly, it enables the functionalization of these scaffolds through C-O, and by extension to C-C or even C-N bond formation.

Asymmetric organocatalytic α-amination of 2-oxindoles with bis(2,2,2-trichloroethyl)azo-dicarboxylate

Bondanza, Mattia,Pescitelli, Gennaro,Mandoli, Alessandro

, p. 2590 - 2594 (2018/05/29)

An enantioselective electrophilic amination of 3-substituted-2-oxindoles is reported, using bis(2,2,2-trichloroethyl)azo-dicarboxylate and commercially available Cinchona alkaloid organocatalysts. The best results were obtained in the reaction of 3-aryl s

Chincona alkaloid-catalyzed enantioselective trifluoromethylthiolation of oxindoles

Yang, Tao,Shen, Qilong,Lu, Long

, p. 678 - 680 (2014/10/16)

An organocatalytic asymmetric trifluoromethylthiolation of 3-aryl or 3-alkyloxindoles employing a trifluoromethyl-substituted thioperoxide as the electrophilic trifluoromethylthiolating reagent was described. Reactions occurred in good to excellent enanti
