A chiral PYBOX-DIPH-Zn(ii) catalyzed enantioselective Mukaiyama-Michael reaction of acyclic silyl enol ethers with 2-enoylpyridine N-oxides has been studied in external additive free conditions at ambient temperature. The methodology offers straightforward access to a variety of functionalized chiral 1,5-dicarbonyl compounds, which could easily be elaborated into synthetically viable pyrones via hydrolysis followed by cyclization. A transition state model has been proposed to explain the stereochemical outcome. The Royal Society of Chemistry 2013.

A catalytic enantioselective Mukaiyama-Michael reaction of 2-enoylpyridine N-oxides has been developed using a simple bis(oxazoline)-copper complex. A variety of silyl enol ethers undergo smooth Michael addition with 2-enoylpyridine N-oxides to furnish the corresponding Michael adducts in high yields with high enantioselectivities (up to 97% ee).
