IMIDAZOLIUM SALT AND ASYMMETRIC SYNTHESIS CATALYST PREPARED THEREWITH, AND METHOD FOR PRODUCING IMIDAZOLIUM SALT

PROBLEM TO BE SOLVED: To provide a variety of optically active imidazolium salts produced efficiently and conveniently. SOLUTION: The present invention provides an imidazolium salt represented by general formula (1). SELECTED DRAWING: None COPYRIGHT: (C)2016,JPOandINPIT

IMIDAZOLIUM SALT, ASYMMETRIC SYNTHESIS CATALYST USING THE SAME, AND METHOD FOR PRODUCING IMIDAZOLIUM SALT

PROBLEM TO BE SOLVED: To provide a novel optically active imidazolium salt for the synthesis of nitrogen-containing heterocyclic carbene as the ligand of organic catalyst and metal catalyst, in particular a bicyclic optically active imidazolium salt, and a method of producing the same. SOLUTION: The present invention provides an imidazolium salt represented by formula (1). (R1-R5 are H, hydrocarbon groups each independently or adjacently forming a ring, alkoxy groups, aryloxy groups, alkylthio groups, arylsulfonyl groups, or the like; X is a substituted/unsubstituted C1-C4 carbon chain, a substituted/unsubstituted N, O, S, or an atom group comprising a combination of Cs optionally substituted with these hetero atoms; Z is a halogen atom, PF6, BF4, ClO4, or BPh4).

Bicyclic imidazoles for modular synthesis of chiral imidazolium salts

The preparation of new chiral bicyclic imidazoles 5 and their transformation into imidazolium salts 6 and 7 are reported. The utility of the salts as precursors for chiral N-heterocyclic carbenes was demonstrated by the synthesis of C-N-C pincer Ni-complex 13h, the structure of which was characterized by single-crystal X-ray analysis.
