Ketenes as Privileged Synthons in the Syntheses of Heterocyclic Compounds. Part 1

Recent advances in ketene chemistry

“…Ketene chemistry remains a very active area of research worldwide, involving both synthetic and mechanistic studies, and has been extensively reviewed. [3][4][5][6][7][8][9][10][11][12][13][14][15] This review describes the most recent work in the area, which is rich in further opportunities. The organization of this review includes separate headings on ketene preparation and on ketene reactions, but since ketenes are usually short-lived intermediates ketene formation and reactivity are usually inextricably mixed, and examples of one almost invariably contain the other.…”

Recent Advances in Application of Amino Acids: Key Building Blocks in Design and Syntheses of Heterocyclic Compounds

“…In continuation of our interest in heterocyclic chemistry (10H(81) 1979, 11T2707, 12H(85)545, 13MI389, 14AHC95, 14AHC176, 14AHC(112)1, 14AHC143,14AHC(113)1), we focus on three-, four-, five-, six-, and seven-membered-ring heterocycles, as well as different bicyclic, tricyclic, and fused heterocyclic systems that have appeared in the literature since 1995 (95AHC1).…”

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.…”
