Facile Construction of an α-(1-Cyclopentenyl)ketone Core by Ruthenium-catalyzed Hydrative Cyclization of 1,6-Allenyne: Total Synthesis of (+)-Myomontanone
Ruthenium-catalyzed hydrativecyclization of 1,6-allenyne in the presence of H2O was demonstrated. The reaction proceeded via nucleophilic attack of H2O to a ruthenacyclopentene intermediate, givin...
