Abstract
[GRAPHICS] The syntheses of both the exo and endo stereoisomers of 7-methyl-7-azabicyc lo[2.2.1]heptan-2-ol were achieved in straightforward fashion, Alternativel y, the intramolecular cyclization of syn-4-N-methylaminocyclohexane 1,2-epo xide was found to give exo-7-methyl-7-azabicyclo-[2,2,1]heptan-2-ol as the sole product. The stereochemistry of the exo isomer was unequivocally confi rmed by X-ray crystallography.
