The single-step atroposelective construction of triaryl α-pyranones with stereogenic 1,2-diaxes was accomplished by NHC organocatalysis. The structure of the substrates and the catalytic system play a critical role in the success of this protocol. DFT calculations were performed to rationalize the origin of the high stereoselectivity.
