This invention relates to preparation of enantio-enriched compounds, and more particularly to enantio-enriched kavalactone compounds and derivatives thereof. The methods provide compounds that are useful as reagents, or building blocks, in the construction of other enantio-enriched compounds.

Diethylzinc and dimethylanilinium tetrakis(pentafluorophenyl)borate were found to catalyze hydroaminations at roomtemperature in high efficiency and very short reaction times. The reactivity of the proposed cationic zinc species, which is assumed to catalyze the reaction, strongly depends on the coordinative abilities of the counterion.
