Abstract
Abstract Synthesis of tropane alkaloids darlingine, chalcostrobamine and isobellendine both in the racemic form and as unnatural enantiomers is described. Enantioselective deprotonation of tropinone, which proceeded with ca 90% ee, was the key step in each of the syntheses. Enantioselectivity was increased in the presence of LiCl.
