155884-24-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 155884-24-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,8,8 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 155884-24:
(8*1)+(7*5)+(6*5)+(5*8)+(4*8)+(3*4)+(2*2)+(1*4)=165
165 % 10 = 5
So 155884-24-5 is a valid CAS Registry Number.

Widely Exploited, Yet Unreported: Regiocontrolled Synthesis and the Suzuki–Miyaura Reactions of Bromooxazole Building Blocks

Solomin, Vitalii V.,Radchenko, Dmytro S.,Slobodyanyuk, Evgeniy Y.,Geraschenko, Oleksandr V.,Vashchenko, Bohdan V.,Grygorenko, Oleksandr O.

, p. 2884 - 2898 (2019/03/07)

An approach to synthesis of 2-, 4-, and 5-bromooxazoles is described. The method was optimized, and its scope was extended to all three isomeric parents, as well as various alkyl- and aryl-substituted bromooxazoles. It was found that direct regiocontrolled lithiation followed by reaction with electrophilic bromine source was common for all substrates and led exclusively to the target substituted 2-, 4- and 5-bromooxazoles on multigram scale. The utility of the multipurpose building blocks obtained in this work was demonstrated in the Suzuki–Miyaura cross-coupling reaction under parallel synthesis conditions.

Oxidation of oxazolines and thiazolines to oxazoles and thiazoles. Application of the Kharasch-Sosnovsky reaction

Meyers,Tavares, Francis X.

, p. 8207 - 8215 (2007/10/03)

Using a modification of the Kharasch-Sosnovsky reaction, the oxidation of oxazolines and thiazolines bearing a variety of 2-alkyl substituents (chiral and achiral) were smoothly oxidized to their corresponding oxazoles and thiazoles, respectively. The key feature involved in the successful implementation of this important oxidation was the use of a mixture of Cu(I) and Cu(II) salts to enhance the oxidation of the intermediate captodative radical, 24. The main limitation of this method was shown when the oxidation failed with oxazolines/thiazolines lacking the carboalkoxy group at C-4.

The Oxidation of 2-Oxazolines to 1,3-Oxazoles

Meyers, A. I.,Tavares, Francis

, p. 2481 - 2484 (2007/10/02)

Oxazolines are readily oxidized to 1,3-oxazoles using NBS/peroxide or light or, more efficiently, by the Kharasch-Sosnovsky Reaction.
