Stericeffects on the deprotonative generation of cyclohexynes and 1,2-cyclohexadienes from cyclohexenyl triflates are described. A cyclohexenyl triflate, which is readily available from nonsubstituted cyclohexanone, was selectively converted to cyclohexyne using magnesium bis(2,2,6,6-tetramethylpiperidide) as base. The generated cyclohexyne was trapped by 1,3-diphenylisobenzofuran to afford the cycloadduct

Deprotonative generation of cyclohexynes, cycloheptynes, and cyclooctynes was achieved by controlling the reactivities of transient anionic species from corresponding enol triflates with magnesium bis(2,2,6,6-tetramethylpiperidide) as a base. The starting enol...
