Synthesis of 3-Substituted and 2,3-Disubstituted Quinazolinones via Cu-Catalyzed Aryl Amidation
摘要:
Cul/4-hydroxy-L-proline catalyzed coupling of N-substituted o-bromobenzamides with formamide takes place at 80 degrees C, affording 3-substituted quinazolinones directly. Under these conditions other amides that were tested only provided simple coupling products, which can be converted into 2,3-disubstituted quinazolinones via HMDS/ZnCl2 mediated condensative cyclization.

5-Methylphenanthridium derivatives were designed, synthesized and evaluated for their in vitro antibacterialactivity and cell division inhibitory activity against various Gram-positive and -negative bacteria. Among them, compounds 5A2, 5B1, 5B2, 5B3, 5C1 and 5C2 displayed the best on-target antibacterialactivity with an MIC value of 4 µg/mL against B. subtilis ATCC9372 and S. pyogenes PS, showing
for the direct arylation of benzothiazole by employing oxime-derived palladacycle 1 as a catalyst was developed. The new catalyst system can be used for 2-arylations by using aryl bromides and iodides. In addition, this method is especially suitable for the intramolecular direct coupling of bromo- and iodoamides, as well aschloroamides, to achieve a rapid synthesis of benzo[c]phenanthridine alkaloids
Practical Synthesis of Phenanthridinones by Palladium-Catalyzed One-Pot C-C and C-N Coupling Reaction: Extending the Substrate Scope to<i>o</i>-Chlorobenzamides
domino reaction proceeds through a sequential C–C and C–N bond-formation process in one pot. This protocol exhibits broad substratescope and affords a series of phenanthridinones in up to 93 % yield. Importantly, the protocol could also be applied for the less reactive o-chlorobenzamides. The approach constitutes the first example of the synthesis of phenanthridinones from this kind of substrate. Moreover
A practical and operationally simple hydrodehalogenation of halogenated carboxylic acid derivatives using a DMSO/HCOONa·2H2O system is developed. This protocol avoids the involvement of light irradiation, electrochemical apparatus, transition metals, radical initiators, strong bases, and other additional additives. Control experiments suggest that HCOONa might function as a hydride donor in the reduction

A novel strategy for the synthesis of 3-methylene-2-arylisoindolin-1-ones through Sonogashira cross-coupling/nucleophilic addition reactions using calcium carbide as a surrogate of gaseous acetylene, 2-bromo-N-(2-bromophenyl)benzamide substrates as starting materials, and copper as a catalyst was described. The salient features of this protocol are the use of a readily available and easy-to-handle
