Total Synthesis of Cochlearol B via a Catellani- and Visible Light-En_x0002_abled [2+2]-Cycloaddition Approach
A new, twelve-step approach towards the mero_x0002_terpenoid cochlearol B is reported. This strategy takes advantage ofa palladium-catalyzed Catellani reaction of a complex chromenyl triflate and a subsequent visible light-mediated -cycloaddition…
