A novel propargylic electrophile-induced tandem intermolecular addition–semipinacol rearrangement was developed for the synthesis of a series of synthetically useful β-propargyl spirocyclic ketones. Its synthetic application was demonstrated by efficient construction of the key tricyclic moiety of daphlongamine E.
