Development of an Allenyne‐Alkyne [4+2] Cycloaddition and its Application to Total Synthesis of Selaginpulvilin A
A new [4+2] cycloaddition of allenyne‐alkyne is developed. The reaction is believed to proceed with forming an α,3‐dehydrotoluene intermediate. This species behaves as a σπ‐diradical to react with a hydrogen atom donor, whereas it displays a zwitterionic reactivity toward weak nucleophiles. The effi...
