Synthesis of axially chiral bipyridine N,N' dioxides and enantioselective allylation of aldehydes.

Abstract

N-oxides possessing the pyridine framework are strong Lewis bases that can activate the C–Si bond of allylhalosilanes to such an extent that they catalyze reactions with aldehydes.

Keywords

• bipyridine N
• N'-dioxides
