1,3-Dipolar Cycloaddition of 1-Methyl-3-oxidopyridinium and Sulfonylethenes. A Synthesis of 2-Tropanols and Monofluorinated 2-Tropanol

Takahashi, Tamiko,Hagi, Toru,Kitano, Kazuyoshi,Takeuchi, Yoshio,Koizumi, Toru

, p. 593 - 596 (2021/10/14)

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.
