A mixture of [PtCl2(CH2CH2)]2 (1 mol %), and EuCl3 (2 mol %) catalyzes the hydroalkylation of 4-pentenyl β-dicarbonyl compounds to form substituted cyclohexanones in moderate to excellent yield with e
TRAPPING REACTION OF ENOLATES FROM LITHIUM DIMETHYLCUPRATE CONJUGATED ADDITION: IMPORTANCE OF STERIC FACTORS AND, PARTICULARLY, OF β-SUBSTITUTION OF ENONE IN THE C- vs. O-ACYLATION

Conjugated addition of lithium dimethylcuprate to α,β-unsaturated ketones gives intermediate enolates which, treated with acetyl chloride, undergo O- and/or C-acylation depending on the substitution at the enone β-carbon.Results agree with the hypothesis that C-acylation proceeds through an intramolecular metal-assisted mechanism.
C-acylation of enolates from lithium dimethylcuprate addition to α,β-unsaturated ketones
Bernasconi,Gariboldi,Jommi,Sisti
, p. 2337 - 2340 (2007/10/02)
The enolates from 1,4 addition of lithium dimethylcuprate to 2-cyclohexenone, 2-cyclopentenone and methyl vinyl ketone, with acetyl chloride, give only C-acylated products and not O-acylated products as previously reported in literature.
