41441-40-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 41441-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,4,4 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 41441-40:
81 % 10 = 1
So 41441-40-1 is a valid CAS Registry Number.

New multicomponent reaction for the direct synthesis of β-aryl-γ-nitroesters promoted by hydrotalcite-derived mixed oxides as heterogeneous catalyst

D'Oca, Caroline R. M.,Naciuk, Fabricio F.,Silva, Jéssica C.,Guedes, Esthéfani P.,Moro, Celso C.,D'Oca, Marcelo G. M.,Santos, Leonardo S.,Natchigall, Fabiane M.,Russowsky, Dennis

, p. 285 - 298 (2016/12/18)

A new approach based on multicomponent/domino combined reactions for the synthesis of γ-nitroesters promoted by a mixed aluminium-magnesium oxides derived from hydrotalcite-like material was developed. Different γ-nitroesters were synthesized in 15-95percent yield using Meldrum's acid, aromatic aldehydes, nitromethane and different alcohols as reagents and solvents. The γ-aminobutyric acid derivatives, Phenibut and Baclofen, were prepared in 63 and 61percent overall yield, respectively, through a two steps synthetic strategy. A mechanistic pathway was proposed based on the gas chromatography mass spectrometry (GC-MS) and electrospray ionization mass spectrometry (ESI-MS) experiments.

One pot domino reaction accessing γ-nitroesters: Synthesis of GABA derivatives

Naciuk, Fabricio F.,Vargas, Debora Z.,D'oca, Caroline R. M.,Moro, Celso C.,Russowsky, Dennis

, p. 1643 - 1653 (2015/03/18)

Michael addition of 1,3-dicarbonyl compounds to nitrostyrenes is efficiently promoted by hydrotalcite [Mg-Al] to afford the respective γ-nitrodicarbonyl adducts. Differently, the addition of Meldrum's acid leads to a direct access of γ-nitroesters through a one pot domino process. GABA derivatives (+/-)-phenibut and (+/-)-baclofen were readily synthesized from the respective nitro adducts.
