- Nickel complexes as efficient catalysts in multicomponent synthesis of tetrahydropyridine derivatives
-
Ni(Salen) complexes as an efficient, homogeneous catalysts revealed a catalytic activity toward the one-pot synthesis of tetrahydropyridine derivatives through the pseudo five-component reactions of aromatic aldehydes, aromatic amines, and β-ketoesters in ethanol at room temperature. Mild reaction conditions, good yields, high diastereoseletivity, operational simplicity, and the absence of tedious separation procedures, clean reaction profiles, high atom economy, inexpensive starting materials, and environmentally benign catalyst are the key advantages of the present MCRs protocol.

- Syntheses of the Carotane-type Terpenoids (+)-Schisanwilsonene A and (+)-Tormesol via a Two-Stage Approach
-
Stereoselective syntheses of terpenoids in a more efficient manner have been a long-term pursuit for synthetic chemists. Herein we describe the two-step, enantiospecific and protecting-group-free synthesis of (+)-schisanwilsonene A from a carotane compound, which was produced in E. coli. We also completed the first enantiomeric synthesis of (+)-tormesol in five steps. The two-stage strategy offers a step- and redox-economical approach to prepare terpene natural products and their analogues.
