Visible Light?Enhanced C?H Amination of Cyclic Ethers with Iminoiodinanes

نویسندگان

چکیده

A two-step protocol allowing the C?H amination of cyclic ethers with iminoiodinanes, followed by reduction resulting intermediate has been developed for preparation amino alcohols. The initial functionalization is accelerated visible light, improving reactivity compared to thermal process performed in dark. effect different substituents on photochemical iminoiodinanes studied both experimentally and computationally. Photophysical measurements DFT calculations were better understand observed reactivities corroborate proposed mechanistic proposal.

Metal-free α-CH amination of ethers with hypervalent sulfonylimino-λ3-bromane that acts as an active nitrenoid.

Hypervalent N-triflylimino-λ(3)-bromane undergoes direct and regioselective α-C-H amination of ethers at room temperature under transition metal-free conditions. Kinetic results, substituent and deuterium isotope effects suggest an asynchronous concerted organonitrenoid transition state with some hydride transfer character, analogous to that for alkane C-H insertions.

Cyclic Ch ronopotentiometry

b An electroanalytical method for studying electrode reactions, called cyclic chronopotenticmetry, in which the applied current is successively reversed a t each t,*ansition, is proposed. A circuit for carrying out automatic current reversals is described. T h e equations for the successive transition times for linear diffusion in a singie clmponent system have been derived and solved, and t h ...

An efficient direct amination of cyclic amides and cyclic ureas.

[reaction: see text] An efficient one-step amination of cyclic amides and ureas has been developed. Treatment of cyclic amides and cyclic ureas with BOP in the presence of DBU in various solvents led to the formation of cyclic amidines and cyclic guanidines in good to excellent yields. Concise syntheses of biologically intriguing kinetin and potent kinase inhibitor olomoucin were thus achieved ...

Cross-dehydrogenative coupling and oxidative-amination reactions of ethers and alcohols with aromatics and heteroaromatics

Cross-dehydrogenative coupling (CDC) is a process in which, typically, a C-C bond is formed at the expense of two C-H bonds, either catalyzed by metals or other organic compounds, or via uncatalyzed processes. In this perspective, we present various modes of C-H bond-activation at sp3 centers adjacent to ether oxygen atoms, followed by C-C bond formation with aromatic systems as well as with he...
