Definitions
- the present invention relates to the aminohydroxylation of olefins. More particularly, the present invention relates to the use of amino-substituted heterocycles as a nitrogen source for enantioselective aminohydroxylation reactions.
- a new generation of nitrogen sources is disclosed which greatly extends the scope of the osmium-catalyzed asymmetric am ohydroxylation (AA). With these nitrogen sources, the AA can now be considered as a means for introducing complex heterocyclic fragments into hydrocarbon backbones when approp ⁇ ate olefinic functionality is present.
- One aspect of the invention is directed to an improved method for converting an olefin to a ⁇ -aminoalcohol using an osmium-catalyzed asymmetnc aminohydroxylation reaction.
- the olefin is enantioselectively aminohydroxylated using chiral hgands and an N-halo alkali salt of an amino-substituted heterocycle as a nitrogen source for producing the ⁇ -ammoalcohol.
- the ammo group of the amino-substituted heterocycle is oxidized to form the N-halo alkali salt.
- the heterocycle of the ammo- substituted heterocycle includes a ⁇ ng lmme conjugated with the amino group to form a planar imidamide system.
- the ⁇ -aminoalcohol produced by the catalytic asymmetric aminohydroxylation reaction has a ⁇ -amino group substituted with the heterocycle.
- the N-halo alkali salt of the amino-substituted heterocycle is represented by the following structure:
- X is a halogen
- Z + is an alkali counter ion
- -( ⁇ -X) " Z + represents the N-halo alkali salt
- -R 1 is one or more radicals, each independently selected from of hydrogen, halogen, aryl, and alkyl groups.
- Y does not include a fused imidazole ring that is coplanar with the planar imidamide system.
- the N-halo alkali salt of the amino-substituted heterocycle is obtained by oxidation of the following amino-substituted heterocycles:
- each R is independently selected from hydrogen, halogen, alkyl, aryl or, together with an adjacent R group, forms a fused aromatic ⁇ ng.
- Figure 1 illustrates an ammohydroxylation with a generalized ammo-substituted heterocycle.
- Figure 2 illustrates the aminohydroxylation with exemplary amino-substituted heterocycles.
- F ⁇ gure3 illustrates the aminohydroxylation of stilbene with va ⁇ ous amino- substituted-heterocycles. Footnotes therein are as follows, [a] Major product from the reaction using (DHQ) 2 PHAL. [b] Isolated yields of pure products after chromatography on silica gel. [c] Determined by chiral HPLC. [d] Concentration in grams per 100 mL of EtOH/CHCL, 1:1.
- Figure 4 illustrates the aminohydroxylation of va ⁇ ous olefins with 2-am ⁇ no-4,6- dimethyltriazine. Footnotes therein are as follows: [a] Major product from the reaction using (DHQ) 2 PHAL. [b] Determined by 'H NMR spectroscopy. [c] Determined by chiral HPLC. [d] Isolated yields from the reaction using the (DHQ) 2 PHAL ligand, where regioisomers are possible, of mixture of both regioisomers. Similar yields and regioselectivities were obtained with the (DHQD) 2 PHAL ligand.
