2,5-Dimethylthiophene (cas: 638-02-8) belongs to benzothiophene derivatives. Benzothiophene is used as starting material for the synthesis of bioactive molecules. The core structure is a part of various pharmaceutical substances and natural products. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.HPLC of Formula: 638-02-8

Preparation of 4-Diazoisoquinolin-3-ones via Dimroth Rearrangement and Their Extension to 4-Aryltetrahydroisoquinolin-3-ones was written by Li, Zhenmin;Chen, Junrong;Wu, Li;Ren, Anni;Lu, Ping;Wang, Yanguang. And the article was included in Organic Letters in 2020.HPLC of Formula: 638-02-8 The following contents are mentioned in the article:

4-Diazoisoquinolin-3-ones were prepared efficiently via TBAB-promoted rearrangement of 4-diazoisochroman-3-imines under mild reaction conditions. The resulted 4-diazoisoquinolin-3-ones could be conveniently applied for the synthesis of 4-aryltetrahydroisoquinolin-3-ones either by the TfOH-catalyzed reaction with electron-rich arenes or by the BF3-promoted reaction with aryl aldehydes. This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8HPLC of Formula: 638-02-8).
