(Chemical Equation Presented) Dynamic Duo: A Lewis basic bidentate phosphine oxide was effective for activating and modulating the properties of Bronsted basic lanthanum aryl oxides. The Lewis base 1/lanthanum aryl oxide system was suitable for anti-selective Mannich-type reactions of trichloromethyl ketones (see scheme), affording unique building blocks for azetidine-2-carboxylic acids as well as β-amino acids.
