Abstract Stereospecific syntheses of a series of chiral epoxides bearing the 1,4‐diyne or 1,4‐enyne unit were achieved through alkylative epoxide rearrangement, which proceeded in two steps: 1) coupling of epoxy tosylate with alkynyltrifluoroborate; and 2) ring‐closure of the resulting intermediate.
