Highly selective bisphosphine ligands for asymmetric hydroformylation of heterocyclic olefins

The bisphosphine ligand 1c is highly efficient and selective for the asymmetric hydroformylation (AHF) of dihydrofuran and pyrrolines. The AHF of 2,3-dihydrofuran yielded the 2-carbaldehyde in up to 93% ee. The remarkable highest regioselectivity of 2,5-dihydrofuran was obtained to date up to 499 beta-isomer/alpha-isomer with ligand 1c. Furthermore, the highest 96% and 92% ee values were accomplished using the same catalytic system in the AHF of N-Boc pyrroline 11 and 14.

An efficient transformation of cyclic ene-carbamates into omega-(N-formylamino)carboxylic acids by ruthenium tetroxide oxidation

The ruthenium tetroxide (RuO4) oxidation of cyclic ene-carbamates resulted in the endo-cyclic carbon-carbon double bond cleavage to afford the corresponding omega-(N-formylamino)carboxylic acids in good yields. Substituted cyclic ene-carbamates derived from (3R)-3-hydroxypiperidine hydrochloride were converted into the N-Boc 4-aminobutyric acids by utilization of the RuO4 oxidation as the key step, which were further transformed into (3R)-4-amino-3-hydroxybutyric acid, an important key intermediate for the synthesis of L-carnitine.

Regiocontrolled synthesis of (hetero)aryl and alkenyl dehydropyrrolidines, dehydropiperidines and azepenes by Ru-catalyzed, heteroatom-directed alpha-C-H activation/cross-coupling of cyclic enamides with boronic acids

The synthesis of alpha-aryl and alkenyl pyrrolidine-, piperidine-, and azepane derivatives, through the intermediacy of cyclic enamides is described. The desired outcome is achieved through ruthenium-catalyzed, site-selective sp2 C-H activation/cross-coupling with aryl and alkenyl boronic acids. The regioselectivity (alpha-sp2vs. alpha-sp3vs. beta-sp2 C-H functionalization) is governed by the rate differences between sp2 and sp3 C-H activation and the necessity for chelation between the ruthenium metal and the carbonyl directing group.

Ion-pairing catalysis in the enantioselective addition of hydrazones to N-acyldihydropyrrole derivatives

We have demonstrated that dihydropyrrole-based enamide derivatives can act as efficient precursors of chiral quaternary N-acyliminium salts under Br¡ãnsted acid catalysis that undergo reactions with hydrazones, the latter participating as masked nucleophilic carbonyl group equivalents. The optimized methodology provides a variety of enantiopure alpha-substituted proline derivatives in excellent yields, being even compatible with disubstituted beta-enamides that generate two contiguous stereocentres.
