Generation of Cyclohexynes from Enol Triflate through Deprotonation by Aluminate Base

摘要

Cyclohexyne has high reactivity and various modes of reactions due to its strained triple bond, which has attracted a great deal of attention in the synthetic community.1 Several methods for generation of cycloalkynes have been developed, however, the conditions are relatively harsh, or preparation of the substrates needs tedious multi-step operations.1
