Synthesis of highly enantioenriched C-TERTIARY amines from boronic esters: Application to the synthesis of igmesine

Better than all the rest: Tertiary boronic esters, readily available using the lithiation-borylation reaction, have been converted into tertiary alkylamines in very high ee. The work has been applied to a short, modular, and fully stereocontrolled synthesis of the pharmaceutical igmesine and chiral 2,2-disubstituted piperidines.

Stereoselective addition of α-sulfinyl carbanions to N-p-tolylsulfinylketimines: Synthesis of optically pure 1,2,2′-trialkyl-2- aminoethanols

The reactions of lithium carbanions derived from both enantiomers of methyl (1) and ethyl p-tolyl sulfoxide (2) with (S)-N-arylsulfinylketimines 3 and 4 took place in a highly stereoselective manner and good isolated yields. The configuration of the carbon bonded to nitrogen relies exclusively on the N-sulfinylimine configuration. When ethyl p-tolyl sulfoxide (2) is use as nucleophile, two chiral centers are created simultaneously, where the configuration of the carbon bonded to the sulfur is mainly controlled by 2. The asymmetric induction increases with the temperature, being total at room temperature in the case of the matched pair of reactants. A non-oxidative Pummerer reaction on the obtained aminosulfoxides allows a straightforward synthesis of optically pure 1,2-ethanolamines with one or two chiral centers, including amino alcohols with a bulky quaternary carbon bonded to the amine group.

Stereoselective Addition Reactions of Chiral N-Benzylidene-p-toluenesulfinamides. Asymmetric Syntheses of β- and γ-Amino Acids

Chiral N-benzylidene-p-toluenesulfinamides 2 were prepared by the reaction of benzonitril with alkyllithium in ether followed by (-)-l-menthyl (S)-p-tolylsulfinate.Treatment of 2 with allylmagnesium bromide in ether at 0 deg C gave the adducts (R)-7 with excellent stereoselectivity.Pure chiral sulfinamides 7 were converted into β- and γ-amino acids in four and five steps, respectively.
