Total Synthesis of rac‐Keramamine C Enabled by Intrinsic H‐Bond‐Induced Conformational Fixation of Amides

European Journal of Organic Chemistry, EarlyView.
The total synthesis of the manzamine alkaloid keramamine C (2) in its racemic form was achieved in 5 steps, with ring‐closing metathesis as the key step. The metathesis is strongly improved by an intramolecular H‐bond‐induced conformational fixation of the amide bond, inducing close proximity of the terminal double bonds in the precursor molecule.

Vinca alkaloids.

International journal of preventive medicine, 2013
Vinca alkaloids are a subset of drugs obtained from the Madagascar periwinkle plant. They are naturally extracted from the pink periwinkle plant, Catharanthus roseus G. Don and have a hypoglycemic as well as cytotoxic effects. They have been used to treat diabetes, high blood pressure and have been used as disinfectants.

Design and Synthesis of Lactose‐Derived Ligands and Their Application in Asymmetric Friedel–Crafts Alkylation

European Journal of Organic Chemistry, EarlyView.
This work describes the synthesis of lactose‐ and glucose‐derived chiral ligands and their application in the catalytic enantioselective Friedel–Crafts alkylation of indole with a series of trans‐β‐nitrostyrenes. The optimal ligand was an acetate protected, lactose‐derived pyridyl imine and its zinc complex afforded ees up to 93% and yields up to 93 ...
