Practical syntheses of 2-azabicyclo[3.1.1]heptane-1-carboxylic (2,4-methanopipecolic), 2-azabicyclo[2.2.2]octane-1-carboxylic (2,5-ethanopipecolic), and 9-azabicyclo[3.3.1]nonane-1-carboxylic (2,6-propanopipecolic) acids are reported. The synthetic schemes are short (five, seven, and five steps, respectively) and result in reasonably high yields of the title compounds. The key step in the syntheses is the

The bicyclo[3.2.1]octane ring system is assembled by a three-step process featuring a thermally induced [4+2] cycloaddition followed by a 1,3-benzodithiolium ion mediated cyclization onto an enol or silyl enol ether double bond.
