A Catalytic Intermolecular Formal Ene Reaction between Ketone-Derived Silyl Enol Ethers and Alkynes

A catalytic formal ene reaction between ketone-derived silyl enol ethers and terminal alkynes is described. This transformation is uniquely capable of bimolecular assembly of 2-siloxy-1,4-dienes and can be used to access β,?-unsaturated ketones containing quaternary carbons in the α-position.

Manganese Carbonyl and Phase Transfer catalysed, Stereospecific Hydroacylation of Allenes to α,β-Unsaturated Ketones

Phase transfer (5 mmol dm-3 NaOH, CH2Cl2, cetyltrimethylammonium bromide) catalysed reaction of allenes with carbon monoxide, decacarbonyldimanganese and methyl iodide affords α,β-unsaturated ketones in a stereospecific process.

Asymmetric Reduction of Carbon-Carbon Double Bonds of Conjugated Enones with Fermenting Bakers' yeast

Bakers' yeast reduction of α-substituted or β,β-disubstituted α,β-unsaturated ketones gave saturated chiral ketones with excellent optical purity, while the β,β-disubstituted derivatives remains intact.

Inducibility of an Enone Reductase System in the Fungus Beauveria sulfurescens: Application in Enantioselective Organic Synthesis

Microbiological reduction of α,β-unsaturated carbonyl compounds is studied.Inducibility of the enone reductase system of Beauveria sulfurescens is reported.The best inducer is shown to be cyclohex-2-en-1-one.An appropriate procedure using induced resting mycelium is developed to reduce substituted cyclohexenones that are shown to be unable to induce the reducing enzyme.Optically pure trans-(2R,6R)-(-)-2,6-dimethylcyclohexan-1-one and trans-(2R,6R)-(-)-2,6-dimethylcyclohexan-1-ol are obtained from (+/-)-2,6-dimethylcyclohex-2-en-1-one along with optically pure (6S)-(-)-2,6-dimethylcyclohex-2-en-1-one.

Catalytic Oxidation of Alk-1-enes to Aldehydes

Aldehydes are the major products of the catalytic oxidation of alk-1-enes with air using a catalyst that comprises (MeCN)2PdClNO2, CuCl2, and a tertiary alcohol.

STEREOCHIMIE DE L'ALKYLATION DE CARBANIONS DERIVES D'α-AMINONITRILES

Alkylations with 2-octyl iodide of carbanions generated in THF by LDA from α-aminonitriles or protected cyanohydrines occur with inversion of configuration and an important racemization; these reactions do not involve radical intermediates.
