Synthesis and stereochemical assignment of exo- and endo-7-methyl-7-azabicyclo[2.2.1]heptan-2-ol.

[formula: see text] The syntheses of both exo and endo stereoisomers of 7-methyl-7-azabicyclo[2.2.1]heptan-2-ol were achieved in straightforward fashion. Alternatively, the intramolecular cyclization of syn-4-N-methylaminocyclohexane 1,2-epoxide was found to give exo-7-methyl-7-azabicyclo-[2.2.1]heptan-2-ol as the sole product. The stereochemistry of the… CONTINUE READING
