Silicon-nitrogen bond formation is an important subfield in main group chemistry, and catalysis is an attractive route for efficient, selective formation of these bonds. Indeed, heterodehydrocoupling and N-silylation offer facile methods for the synthesis of small molecules through the coupling of primary, secondary, and tertiary silanes with N-containing substrates such as amines, carbazoles, indoles, and pyrroles. However, the reactivity of these catalytic systems is far from uniform, and critical issues are often encountered with product selectivity, conversions, substrate scope, catalyst activation, and in some instances, competing side reactions. Herein, a catalogue of catalysts and their reactivity for Si-N heterodehydrocoupling and N-silylation are reported.

An atroposelective coupling of indoles with chiral amino acid-based sulfonamides mediated by hypohalides is described. A series of 2-amido-3-haloindoles with a C-N chiral axis are delivered using this strategy. The C3 halogen atoms can facilitate further transformation. Various functionalities, such as carbonyl, phosphine, aryl, and alkenyl groups, can be introduced into the C3 position of indoles. These structurally diverse and axially chiral indole derivatives can find further synthetic utilities. It can be exemplified with an axially chiral phosphine, which serves as a ligand in Pd-catalyzed cross couplings.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.

Gold(I)-Catalyzed Cascade Cyclization of Anilines with Diynes: Controllable Formation of Eight-Membered Ring-Fused Indoles and Propellane-Type Indolines

Heterocycle-fused indoles or indolines are distributed widely in a variety of natural products, bioactive agents, and pharmaceuticals. Herein, we describe the development of gold catalyzed cascade reactions of anilines with diynes to form eight-membered ring-fused indoles and propellane-type indolines, both of which proceed through an intramolecular 5-endo-dig hydroamination followed by an 8-endo-dig cycloisomerization. Controllable formation of eight-membered ring-fused indoles and propellane-type indolines was achieved through selection of the ligands and/or solvents. Protic solvents such as alcohols or IPr ligand favored the formation of eight-membered ring-fused indoles, whereas the use of Buchwald’s type ligands and/or nonpolar solvents gave propellane-type indoline predominantly. This reaction provides rapid access to two types of fused nitrogen heterocycles from simple aniline derivatives.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 148408-66-6. The above is the message from the blog manager. SDS of cas: 148408-66-6.

Photocatalytic Intramolecular [2+2] Cycloaddition of Indole Derivatives via Energy Transfer: A Method for Late-Stage Skeletal Transformation

Visible light-promoted dearomative [2 + 2] cycloaddition of indole derivatives tethered with olefins at the N1 position has been considered thermodynamically unfeasible due to the high triplet excited-state energies. We describe visible light-promoted [2 + 2] cycloaddition with concomitant dearomatization of indole derivatives tethered with olefins at the N1 position via the energy transfer process, providing cyclobutane-fused polycyclic indoline derivatives that are potentially useful in drug design and discovery. These cyclobutane-fused indoline-based polycycles are obtained in high yields and with good diastereoselectivities (>99:1). The key to the success of the reaction is the formation of H-bond(s) between N-alkenoylindole and solvent, enabling the reduction of the triplet energy of the indole derivatives, which greatly improved the efficiency of the protocol. The applicability of the method is demonstrated by late-stage skeletal diversification of indole-containing bioactive molecules, which provides a powerful strategy for the rapid skeleton remodeling. DFT calculations were used to give a deep understanding of the reaction pathways.
