I found the field of Chemistry very interesting. Saw the article Palladium Catalyzed Cross-Dehydrogenative Coupling/Annulation Reaction: A Practical and Efficient Approach to Hydroxyisoindolo[1,2-b]quinazolinone published in 2019. SDS of cas: 93-02-7, Reprint Addresses Dabiri, M (corresponding author), Shahid Beheshti Univ, Fac Chem & Petr Sci, Dist 1,Daneshjou Blvd, Tehran 1983969411, Tehran Province, Iran.. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde
The palladium-catalyzed cross-dehydrogenative coupling (CDC) followed by an intramolecular cyclization between arylquinazolinones and aldehydes has been described. This viable transformation provides a variety of novel substituted hydroxyisoindolo[1,2-b]quinazolinone compounds in moderate to good yields. Additionally, the reaction is performed with toluene in place of benzaldehyde by using an excess amount of tert-butyl hydroperoxide (TBHP) as the oxidant in good yield.
About 2,5-Dimethoxybenzaldehyde, If you have any questions, you can contact Dabiri, M; Lehi, NF; Movahed, SK; Khavasi, HR or concate me.. SDS of cas: 93-02-7
