Tetrahedron Letters, 1994, 35(22):3653-3656.
Synthesis of Pyranotropanes via Enantioselective Deprotonation Strategy.[Reference: WebLink]

METHODS AND RESULTS:
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.
