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...

A reinvestigation ofEumorphia prostata afforded two new furanosesquiterpenes. The structure of eumorphistonol has been determined by synthesis. Two further furans were prepared and the absolute configuration of the main compound was deduced by a chiral synthesis.
