A series of 2-methylchromanone derivatives have been prepared by using a novelpalladium-catalyzed Wacker-type oxidative cyclization, in which a 1,5-hydride alkyl to palladium migration and a direct chirality transfer were involved.

A new method for one-pot synthesis of β-substituted and β,β-disubstituted α,β-unsaturated methyl ketones from homoallyl alcohols by sequential PdCl2/CrO3-promoted Wacker process followed by an acid-mediated dehydration reaction has been developed. Remarkably, internal homoallyl alcohols delivered regioselectively nonconjugated unsaturated carbonyl compounds under the same protocol. A new starting material-based
