A facile and efficient process for the preparation of various tertiary aminobenzenes and carbazole derivatives via photoinduced cross-coupling of amines with 1,2-diiodobenzene is reported. Mechanistic investigations indicate that the transformation proceeds via nucleo-philic addition of an amine to the benzyne intermediate accompanied with a proton transfer process, followed by an oxidative cyclization of the generated diphenylamine to furnish the corresponding carbazole products.

A copper-catalyzed intramolecular amidation of unactivated C(sp3)-H bonds to construct indoline derivatives has been developed. Such an amidation proceeded well at primary C-H bonds preferred to secondary C-H bonds. The transformation owned a b

Light-induced transformation of atropisomeric and achiral enones displays divergent reactivity. Photocyclization leading to 3,4-dihydroquinolin-2-one was observed with achiral enone carboxamide, whereas the atropisomeric enone carboxamides underwent hydro
Reductive N-methylation of amines with calcium hydride and Pd/C catalyst

, p. 3002 - 3005 (2016/07/06)
The methylation of amines by paraformaldehyde in the presence of calcium hydride as a source of hydrogen and palladium on charcoal as catalyst was studied. Depending on the quantity of paraformaldehyde, monomethylated and dimethylated amines were selectively and efficiently prepared in one pot with good yields.
Enantiospecific photochemical Norrish/Yang type II reaction of nonbiaryl atropchiral α-oxoamides in solution-axial to point chirality transfer

(Chemical Equation Presented) α-Oxoamides 1 with o-tert-butyl substitution on the N-phenyl moiety were found to be stable axially chiral atropisomers. These axially chiral α-oxoamides undergo enantiospecific photochemical γ-Hydrogen abstraction in CHClsu
Rotational features of carbon-nitrogen bonds in axially chiral o-tert- butyl anilides and related molecules. Potential substrates for the 'prochiral auxiliary' approach to asymmetric synthesis
Curran, Dennis P.,Hale, Gregory R.,Geib, Steven J.,Balog, Aaron,Cass, Quezia B.,Degani, Ana Luiza G.,Hernandes, Marcelo Z.,Freitas, Luiz Carlos G.

A new strategy for asymmetric induction termed the 'prochiral auxiliary' approach is introduced. Reactions of acylating agents with prochiral N- methyl-o-tert-butyl aniline provide anilides that are axially chiral by virtue of restricted rotation about th
