3-phenyl-5-(phenylethynyl)isoxazole is a complex organic chemical compound characterized by a unique molecular structure. It features an isoxazole ring, which is a five-membered heterocyclic ring containing one oxygen atom and one nitrogen atom. The compound is further distinguished by a phenyl group attached to the 3rd position of the isoxazole ring and a phenylethynyl group, which is a phenyl group connected to an ethynyl (acetylene) group, attached to the 5th position. This arrangement endows the molecule with specific electronic and steric properties that can be relevant in various chemical and pharmaceutical applications, such as in the synthesis of more complex molecules or as a potential intermediate in the development of new drugs. The compound's structure and properties make it a subject of interest in organic synthesis and medicinal chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 6797-27-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,9 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6797-27:
(6*6)+(5*7)+(4*9)+(3*7)+(2*2)+(1*7)=139
139 % 10 = 9
So 6797-27-9 is a valid CAS Registry Number.

General Platform for the Conversion of Isoxazol-5-ones to 3,5-Disubstituted Isoxazoles via Nucleophilic Substitutions and Palladium Catalyzed Cross-Coupling Strategies

A general platform for the conversion of isoxazol-5-ones to 3,5-disubstituted isoxazoles has been developed via a two-step strategy. The first step leads to the formation of 5-(pseudo)halogenated isoxazoles, while in the second, a variety of heteroalkyl-, heteroaryl-, alkyl-, alkenyl-, alkynyl- and aryl-chains can be installed via nucleophilic substitutions or palladium catalyzed cross-coupling reactions.

A direct access to isoxazoles from ynones using trimethylsilyl azide as amino surrogate under metal/catalyst free conditions

A general method for isoxazoles from readily available ynones using trimethylsilyl azide as an amino surrogate, likely via an unprecedented hydroazidation of the alkyne and denitrogenative cyclization, is demonstrated. The method neither required any cata
