Chan, CK; Lai, CY; Wang, CC in [Chan, Chieh-Kai; Lai, Chien-Yu; Wang, Cheng-Chung] Acad Sinica, Inst Chem, Taipei 115, Taiwan published TMSOTf-catalyzed synthesis of substituted quinazolines using hexamethyldisilazane as a nitrogen source under neat and microwave irradiation conditions in 2020.0, Cited 84.0. Recommanded Product: 93-02-7. The Name is 2,5-Dimethoxybenzaldehyde. Through research, I have a further understanding and discovery of 93-02-7.
In this article, we report an efficient and mild synthetic route for the construction of substituted quinazolines from functionalized 2-aminobenzophenones with various benzaldehydes usingcat. TMSOTf and hexamethyldisilazane (HMDS) under neat, metal-free and microwave irradiation conditions in which gaseous ammonia was formedin situ. This synthetic protocol provided the desired quinazolines with a broad substrate scope in good to excellent yields. Some structures were confirmed by X-ray single-crystal diffraction analysis.
Recommanded Product: 93-02-7. Bye, fridends, I hope you can learn more about C9H10O3, If you have any questions, you can browse other blog as well. See you lster.
