The synthesis of O/S-heterocycles starting from β-nitrostyrenes: A recent update

Developments and applications of α-bromonitrostyrenes in organic syntheses

“…Recently, various research teams, such as Jakubec, 25 Gao, 26 Lee, 27 Halimehjani, 28 Shen, 29 and Zhang 30 reported the organic transformations of nitrostyrenes. In this review, we have specifically discussed the use of α-bromonitrostyrenes in various types of catalytic systems, such as organocatalysis, metal catalysis and base catalysis as well as catalyst-free reactions.…”

Development of an Optimized Process for 2,4-Dichloro-5-fluoroacetophenone: A Key Intermediate of Ciprofloxacin

“…Furthermore, in the nitrochlorination reaction, we employed a mixed acid spray tower to absorb nitrogen oxides for the preparation of nitrososulfuric acid, thus achieving resource utilization. Finally, in the acetylation reaction, magnetic materials featuring both Bronsted and Lewis acid sites were utilized to immobilize the bisacid site catalyst [HPhIm][FeCl 4 ]/MPNs, replacing the traditional AlCl 3 approach. − …”

Concise synthesis of pyrrolo[3,4-c]quinolines via a P(NMe2)3-catalyzed [4 + 2] annulation followed by a Zn/AcOH-mediated reduction–hydroamination–isomerization

“…β-Nitrostyrenes bearing both a C–C double bond and an electron-withdrawing nitro group have proven to be versatile synthons participating in diverse reactions. 8 Because of the activating effect of the nitro group, the C–C double bond on β-nitrostyrene acts as a Michael acceptor in conjugate addition reactions, or as a dienophile in cycloaddition reactions. Furthermore, the nitro group can be converted into various functional groups, such as carbonyls, carboxylic acids, oximes, and nitriles.…”
