Enantioselective Copper(I)/Chiral Phosphoric Acid Catalyzed Intramolecular Amination of Allylic and Benzylic C?H Bonds

Radical-involved enantioselective oxidative C?H bond functionalization by a hydrogen-atom transfer (HAT) process has emerged as a promising method for accessing functionally diverse enantioenriched products, while asymmetric C(sp3)?H bond amination remains a formidable challenge. To address this problem, described herein is a dual CuI/chiral phosphoric acid (CPA) catalytic system for radical-involved enantioselective intramolecular C(sp3)?H amination of not only allylic positions but also benzylic positions with broad substrate scope. The use of 4-methoxy-NHPI (NHPI=N-hydroxyphthalimide) as a stable and chemoselective HAT mediator precursor is crucial for the fulfillment of this transformation. Preliminary mechanistic studies indicate that a crucial allylic or benzylic radical intermediate resulting from a HAT process is involved.

MANUFACTURING METHOD OF BROMINATED CYCLOPROPANES

PROBLEM TO BE SOLVED: To provide a manufacturing method capable of simply providing bromoalkyl cyclopropanes in an industrial scale. SOLUTION: There is provided a manufacturing method of bromoalkyl cyclopropanes represented by the formula (3) or the formula (4) by reacting corresponding alcohols and HBr dissolved in an aprotic solvent such as 1,4-dioxanes and substituting a hydroxyl group by Br. (3) (4), where R1 is H, a C1 to 10 substituted/unsubstituted linear/branched alkyl group, a C3 to 10 substituted/unsubstituted cyclic alkyl group, R2 is a substituted/unsubstituted phenyl group and n is an integer of 1 to 10.

One-pot synthesis of fused benzo[c]carbazoles by photochemical intramolecular annulation of 3-acyl-2-haloindoles with tethered styrenes

An efficient procedure for the synthesis of fused benzo[c]carbazoles has been achieved in moderate to high yields by the one-pot photochemical annulation of 3-acyl-2-haloindoles with tethered styrenes by photoinduced electron-transfer coupling, electrocyclic reactions, and deacylative aromatization in the presence of pyridine. Fused furo[2,3-c]carbazoles were also synthesized under the same conditions. 5,6-Dihydrobenzo[c]pyrrolo[1,2,3-lm] carbazoles were oxidized by DDQ to afford aromatic benzo[c]pyrrolo[1,2,3-lm] carbazole products in moderate to high yields.
