Influence of phase transfer catalyst structure on the E : Z ratio in the O-alkylation of an enolate

Both C- vs. O-alkylations and Z vs. E enol ether formation from 2-methyl-1,3-diphenylpropane-1,3-dione (1) can be influenced by the structure of the phase transfer catalyst. O-Methylation is the major process in the PTC reaction of 1 with dimethyl sulfate

Versatile CuI/Pd0 dual catalysis for the synthesis of quaternary α-allylated carbonyl compounds: Development, mechanistic investigations and scope

We report herein a versatile cooperative dual catalysis reaction based on a CuI/Pd0 system. Mechanistic investigation shows that every component plays a crucial role in determining the reaction outcome. The reaction is successfully extended to various substrates; such as α,β-unsaturated ketones, malonates and coumarins. The strategy tolerates different substitution patterns and affords good yields for each family of substrates.
