Chiral nitrogen-metal complexes for the asymmetric reduction of ketones

Chiral cobalt-diamine complexes have been prepared and tested in catalytic reduction of β-ketoesters and ketones with molecular hydrogen or hydride transfer reduction (HTR). Modest to high conversions, but low e.e.s were obtained in the first case, wherea

The invention discloses a 2-[(2R, 6S)-6-[(2S)-2-hydroxy-2-phenethyl]-1-pipecoline]-1-hypnone synthesis method, and belongs to the field of organic synthesis. (1S, 2S)-1, 2-diphenyl diaminoethane serving as a raw material is subjected to acylation, substitution and the like to prepare chiral amine catalysts. A main route totally includes two steps: synthesizing glutaraldehyde, benzoyl acetic acid and methylamine hydrochloride to form cis-lobelanine; performing asymmetric selective reduction synthesis of 2-[(2R, 6S)-6-[(2S)-2-hydroxy-2-phenethyl]-1-pipecoline]-1-hypnone under mild reaction conditions and under the action of the catalysts. The raw material in the whole process route is cheap and easy to obtain, the catalysts can be recycled and can continue to be used, and the synthesis method is low in cost, simple in process, mild in reaction condition, convenient in operation and high in total yield.

L-Pipecolinic acid derived Lewis base organocatalyst for asymmetric reduction of N-aryl imines by trichlorosilane: Effects of the side amide group on catalytic performances

A series of N-formamides derived from pipecolinic acid have been synthesized and tested as Lewis base catalysts for the enantioselective reduction of N-aryl imines by trichlorosilane. Through the investigation of the structure-efficacy relationship between the side amide group and catalytic performance, several highly effective catalysts were discovered. In particular, arylamido-type catalyst 5i and non-arylamido-type catalyst 6c exhibited high reactivity and enantioselectivity, furnishing the reduction of a wide variety of N-aryl imines with high isolated yields (up to 98%) and ee values (up to 96%) under mild conditions. Moreover, these two catalysts complement each other in terms of their tolerances to nonaromatic ketimines and non-methyl ketimines. The Royal Society of Chemistry 2013.
