-
Paragraph 0029-0034, (2017/09/01)
The invention belongs to the filed of chemical synthesis and discloses a preparation method of 5-cyano-3-(4-chlorobutyl)-benzpyrole. The method comprises the following steps: synthesizing 5-cyano-3-(4-chlorobutyl)-benzpyrole from 4-cyano phenyl diazoamino tetrafluoroborate as a raw material and a zinc reagent solution of 6-bromine chloride hexane under an acid condition. The 5-cyano-3-(4-chlorobutyl)-benzpyrole has the advantages of being high in yield, simple in process, green and environmental-friendly, and has very good industrialization prospect.

A Ni-catalyzed Negishi cross-coupling with 1,1-disubstituted styrenyl aziridines has been developed. This method delivers valuable β-substituted phenethylamines via a challenging reductive elimination that affords a quaternary carbon. A novel electron-deficient olefin ligand, Fro-DO, proved crucial for achieving high rates and chemoselectivity for C-C bond formation over β-H elimination. This ligand is easy to access, is stable, and presents a modular framework for reaction discovery and optimization. We expect that these attributes, combined with the fact that the ligands impart distinct electronic properties to a metal, will support the invention of new transformations not previously possible using established ligands.
