Significant Attention

Copper-catalyzed (or -mediated) asymmetric coupling reactions have received significant attention over the past few years. Especially the coupling reactions of aryl or alkyl halides with nucleophiles became a very powerful tool for the formation of C–C, C–N, C–O and other carbon–heteroatom bonds as well as for the construction of heteroatom-containing ring systems. This review summarizes the recent progress in copper-catalyzed asymmetric coupling reactions for the formation of C–C and carbon–heteroatom bonds.

Recent Advances

Imines, versatile intermediates for organic synthesis, can be exploited for the preparation of diverse classes of biologically active benzazoles. Because of the special characteristics of the C=N bond, imines can be simultaneously used in the synthesis of 1,3-benzazoles and 1,2-benzazoles. With the development of imine synthesis, a variety of novel cascade reactions for benzazole synthesis have been reported in the last decade. Therefore, there is a strong need to elucidate the recent progress in the formation of various classes of benzazoles, including benzimidazoles, benzoxazoles, benzothiazoles, indazoles, and benzisoxazoles, via imines obtained by condensation reactions or oxidative/ redox coupling reactions

Exonic circular RNAs (circRNAs) have been discovered in all kingdoms of life. In many cases, the details of circRNA function and their involvement in cellular processes and diseases are not yet fully understood. However, the past few years have seen significant developments in bioinformatics and in experimental protocols that advance the ongoing research in this still-emerging field. Sophisticated methods for circRNA generation in vitro and in vivo have been developed, allowing model studies into circRNA function and application. We here review the ongoing circRNA research, giving special attention to recent progress in the field.

AbstractRecently, intense efforts have been dedicated to the development of novel synthetic strategies to access aromatic amines due to their importance in the pharmaceuticals, agrochemicals, materials, and natural product areas. Although numerous transition-metal-catalyzed C–N formation strategies have been described for the preparation of aromatic amines in the past few decades, complementary methods under transition-metal-free conditions are still required. We present the recent advances in the exploration of innovative amination approaches via C(sp2)–O/C(sp2)–S bond cleavage in this review.1 Introduction2 Stoichiometric Base-Promoted Amination3 Base-Catalyzed Amination4 Photoredox-Catalyzed Amination5 Acid-Promoted Amination6 Conclusion and Perspectives
