Tandem 6π-Azatriene Electrocyclization of Fused Amino-cyclopentenones: Synthesis of Functionalized Pyrrolo- and Indolo-quinoxalines was written by Saini, Kapil Mohan;Saunthwal, Rakesh K.;Kumar, Ankit;Verma, Akhilesh K.. And the article was included in Organic Letters in 2021.SDS of cas: 1186603-47-3 The following contents are mentioned in the article:

A tandem 6π-azacyclization approach for the synthesis of diversified pyrrolo/indolo[1,2-a]quinoxalines from amino-cyclopentenones has been developed. The reaction proceeds through a trifluoroacetic-acid-mediated 6π-electrocyclization and concomitant opening of the cyclopentenone ring. The advantageous features of the developed chem. include transition-metal-free conditions, operational simplicity, and a broad substrate scope. Further X-ray crystallog. studies confirm the assigned structures of the fused heterocycles. This study involved multiple reactions and reactants, such as 5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3SDS of cas: 1186603-47-3).

5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).SDS of cas: 1186603-47-3
