Regioisomeric 3,7,7-trimethylbicyclo[4.1.0]heptanols and their acetoacetates with substituted 1,2,3-triazole fragments were synthesized via azide–alkyne cycloaddition reactions of azidocaranols and mono-substituted acetylenes. A one-pot synthesis of symmetric and asymmetric esters of carane-type 2,6-dimethylpyridine-3,5-dicarboxylic acid was proposed.
