Bromocyclization of Unsaturated Oximes. Synthesis of Five-Membered Cyclic Nitrones (Pyrroline N-Oxides)* [1]
The cyclization of a ribose-derived pentenose oxime with various halogen electrophiles showed bromine to be the most effective reagent, leading to 80% of L-lyxo/D-ribo-pyrroline N-oxides in an 84:16 diastereomeric ratio. In order to explore the scope of this facile process, several other γ ,δ unsaturated oximes were submitted to this reaction. Depending on the substitution pattern, 23 – 87%, yi...
متن کاملOrganocatalytic asymmetric Michael reaction of cyclic 1,3-dicarbonyl compounds and alpha,beta-unsaturated ketones--a highly atom-economic catalytic one-step formation of optically active warfarin anticoagulant.
As optically active drugs become increasingly important for the treatment of diseases in patients, still more enantiopure drugs are introduced to the market either as new drugs or as the result of a racemic switch. An important goal for asymmetric catalysis is to develop new reactions that afford optically active compounds from simple and easily available starting materials and catalysts. Howev...
متن کاملCatalytic asymmetric addition of diphenylzinc to cyclic , -unsaturated ketones
We have examined the use of our bis(sulfonamide) diol ligand (1) in the asymmetric addition of phenyl groups to cyclic , -unsaturated ketones. Good to excellent enantioselectivities have been obtained with cyclic enones bearing alkyl substituents in the 2 position (71–97% enantiomeric excess). Furthermore, excellent enantioselectivities have been observed in the asymmetric phenylation of cyclic...
متن کاملAsymmetric Organocatalytic Reactions of α, β-Unsaturated Cyclic Ketones
The 1,4-conjugate addition of nucleophiles to α,β-unsaturated carbonyl compounds represents one fundamental bond-forming reaction in organic synthesis. The development of effective organocatalysts for the enantioselective conjugate addition of malonate, nitroalkane and other carbon and heteroatom nucleophiles to cycloenones constitutes an important research field and has been explored in recent...
متن کاملHighly chemoselective copper-catalyzed conjugate reduction of stereochemically labile alpha,beta-unsaturated amino ketones.
Highly chemoselective conjugate reduction of chiral alpha,beta-unsaturated amino ketones has been developed by using triisopropyl phosphite ligated copper hydride complex. The highlights of the method are wide substrate compatibility and exceptional chemoselectivity.
