Bischler–Napieralski Reaction in the Syntheses of Isoquinolines∗

Current advances in the synthesis and biological potencies of tri- and tetra-substituted 1H-imidazoles

“…A literature survey revealed several useful reviews on the synthesis of imidazoles [22][23][24][25][26]-among them a comprehensive review published in Tetrahedron in 2007 [22]. We are involved in heterocyclic chemistry [27][28][29][30][31][32][33][34] and focus on enhancing recent developments and progress in organic chemistry especially in the area of name reactions [35][36][37][38]. In line with our interest, considering the importance of the imidazole moiety and prompted by the mentioned comprehensive review [22], we aimed for an update and extension of its usefulness focusing on the synthesis of imidazoles.…”

Fischer indole synthesis applied to the total synthesis of natural products

“…25,[30][31][32][33] Because of the large number of biologically fascinating natural products containing poly-substituted indole moieties, FIS has attained signicant synthetic attention. 34 In continuation of our interest in applications of name reactions in the total synthesis of natural products [35][36][37][38][39][40][41][42][43][44][45][46][47] and in the synthesis of heterocyclic systems, [48][49][50][51][52] in this review, we try to highlight the applications of FIS in total synthesis of biologically active natural products.…”

Caro's Acid-Silica Gel Catalyzed Regioselective Ring Opening of Epoxides with Indoles and Imidazoles under Solvent-Free Conditions

“…CA-SiO2 catalyzed reaction, enhancing the reactivity and selectivity for several kind of reactions , such as oxidative coupling of thiols to disulfides [15], conversion of thioamides into amides [ 16], carbonyl compounds from oximes [ 17], synthesis xanthen [ 18] and synthesis tetrahydrobenzo[b]pyran [ 19], have been reported [20]. We are interested in heterocyclic chemistry [21][22][23][24][25][26]. We have also reported in ring opening of epoxides using different catalysts [ 27].…”
