Cycloadditions of cyclohexynes and cyclopentyne. [PDF]
, 2014 We report the strategic use of cyclohexyne and the more elusive intermediate, cyclopentyne, as a tool for the synthesis of new heterocyclic compounds. Experimental and computational studies of a 3-substituted cyclohexyne are also described.
