A convenient approach to the synthesis of diverse difluorinated nitrogen-containing polycycles via a copper-catalyzed radical cascade annulation of amine-containing olefins and ethyl bromodifluoroacetate was developed. Three new bonds, including a Csp3 ?CF2 and two C?N bonds, are forged simultaneously in this strategy. Through this strategy, a series of difluorinated pyrrolizidine and indolizidine derivatives have been conveniently synthesized in good yields. (Figure presented.).
Rate acceleration and diastereoselectivity in chelation-controlled indium-promoted Barbier allylation of pyridine-2- and quinoline-2-imines in aqueous solvents

The imines generated in situ from 2-pyridinecarboxaldehyde/2- quinolinecarboxaldehyde and aryl amines undergo indium-mediated Barbier allylation in aqueous media to provide homoallylic amines. Crotyl and cinnamyl bromides lead to diastereoselective allyla
Indium-mediated barbier reactions of azides: A facile synthesis of N-allylamine derivatives

A nickel-catalyzed aminofluoroalkylative cyclization of unactive alkenes with iododifluoromethyl ketones was developed to construct versatile difluoroalkylated Nitrogen-containing heterocycles including aziridines, pyrrolidines and piperidines in moderate to high yields. This method features a broad substrate scope and has been demonstrated on gram scale.

Paragraph 0079; 0083-0084, (2021/09/21)
The invention provides a fused ring compound and a preparation method thereof. In the method, precursor compounds A and B prepared under the conditions of triethylamine as a base, DMF as a solvent andpalladium acetate and triphenylphosphine as a catalyst react to generate a series of new fused ring compounds with a unique stereoselectivity. Compared with the conventional fused ring compound, thefused ring compound prepared by the invention has a more complicated structure, a mild reaction condition and a high reaction yield. The fused ring compound also shows a broader prospect of use in chemical production and clinical medicine.
