Asymmetric Total Syntheses of (?)-α-Lycorane, (?)-Zephyranthine, and Formal Synthesis of (+)-Clivonine

An asymmetric route to (?)-α-lycorane and (?)-zephyranthine, and a formal total synthesis of (+)-clivonine were achieved. A pivotal intermediate, which serves as a potent precursor for the divergent syntheses of these natural products, was accessed by a diastereoselective Pd-catalyzed cinnamylation of an N-tert-butanesulfinyl imine.

Catalytic asymmetric hydrogenation of α-arylcyclohexanones and total synthesis of (-)-α-lycorane

An efficient catalytic asymmetric hydrogenation of racemic α-arylcyclohexanones with an ethylene ketal group at the 5-position of the cyclohexane ring via dynamic kinetic resolution has been developed, giving chiral α-arylcyclohexanols with two contiguous
