, p. 3681 - 3690 (1995)
The facile and efficient multigram synthesis of (±)-tropan-2-one 1 was achieved in six steps (65% overall yield) from N-methyl-3-oxopyridyl hydroiodide 3.

2α- and 2β-Tropanols were synthesized by 1,3-dipolar cycloaddition of phenyl vinyl sulfone and 1-methyl-3-oxidopyridinium regio- and stereoselectively.The method was extended to a preparation of 6α-fluoro-2β-tropanol from 1-(benzenesulfonyl)-1-fluoroethene.
