235783-18-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 235783-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,5,7,8 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 235783-18:
(8*2)+(7*3)+(6*5)+(5*7)+(4*8)+(3*3)+(2*1)+(1*8)=153
153 % 10 = 3
So 235783-18-3 is a valid CAS Registry Number.

CuCl2-Mediated Oxidative Intramolecular α-Arylation of Ketones with Phenolic Nucleophiles via Oxy-Allyl Cation Intermediates

Aota, Yusuke,Kano, Taichi,Maruoka, Keiji,Mochimatsu, Takuto

supporting information, p. 3816 - 3819 (2020/10/19)

α-Functionalization of ketones in an umpolung fashion can be achieved by nucleophilic addition to the oxy-allyl cation intermediate. However, applicable carbon nucleophiles are limited to ones with high nucleophilicity. Additionally, introduction of a lea

Hypervalent iodine(III)-induced intramolecular cyclization of α-(aryl)alkyl-β-dicarbonyl compounds: A convenient synthesis of benzannulated and spirobenzannulated compounds

Arisawa,Ramesh,Nakajima,Tohma,Kita

, p. 59 - 65 (2007/10/03)

A novel hypervalent iodine(III)-induced direct intramolecular cyclization of α-(aryl)alkyl-β-dicarbonyl compounds has been described. Both meta- and para-substituted phenol ether derivatives containing acyclic or cyclic 1,3-dicarbonyl moieties at the side chain undergo this reaction in a facile manner. The reactions afford benzannulated and spirobenzannulated compounds that are of biological importance. The reaction is found to be general, mild, and high yielding. The mechanism of the reaction has been shown to involve a cation radical intermediate.
