Abstract:A catalytic asymmetric Michael addition/annulation process between pyrazolones and enynones towards enantioenriched pyranopyrazoles was developed. Key features include the development of a cinchona alkaloid with C6' steric bulk as a competent catalyst and the observation of a unique stereospecific deuteration alpha to the keto group via a conducted tour pathway.
