221148-26-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 221148-26-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,1,4 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 221148-26:
(8*2)+(7*2)+(6*1)+(5*1)+(4*4)+(3*8)+(2*2)+(1*6)=91
91 % 10 = 1
So 221148-26-1 is a valid CAS Registry Number.

Enantioselective Fluorination of α-Branched β-Ynone Esters Using a Cinchona-Based Phase-Transfer Catalyst

Arimitsu, Satoru,Iwasa, Satsuki,Arakaki, Ryunosuke

supporting information, p. 12804 - 12812 (2020/10/09)

Herein, we report the fluorination of α-branched β-ynone esters to afford their corresponding quaternary fluorinated products with good enantioselectivity (ee = 73-90%) using a cinchona-based phase-transfer catalyst. α-Branched β-ynone esters possess a highly acidic α-proton and form their corresponding enolate as a single isomer, which allows the enantioselective fluorination reaction to occur under standard cinchona-based phase-transfer catalyst conditions. Moreover, the obtained α-fluorinated product can be treated with [(SPhos)AuNTf2] (1 mol %) to afford a fluorinated 3,5-diketo carboxylic acid.

FORMYLATED XANTHOCILLIN ANALOGUES AS NEUROPROTECTIVE AGENTS

Oligosubstituted pyrroles directly from substituted methyl isocyanides and acetylenes

Lygin, Alexander V.,Larionov, Oleg V.,Korotkov, Vadim S.,De Meijere, Armin

supporting information; experimental part, p. 227 - 236 (2009/06/20)

The formal cycloaddition of α-metallated methyl isocyanides 1 onto the triple bond of electron-deficient acetylenes 2 represents a direct and convenient approach to oligosubstituted pyrroles 3. The scope and limitations of this reaction (24 examples, 2597 % yield) are reported along with an optimization of the reaction conditions and a rationalization of the mechanism. In addition, a related newly developed CuI-mediated synthesis of 2,3-disubstituted pyrroles by the reaction of copper acetylides derived from unactivated terminal alkynes with substituted methyl isocyanides is described (11 examples, 5-88% yield).
