## Abstract The cyclization of (8‐oxo‐2‐octenyl)boronates having benzyloxy substituents in the chain linking the two functional groups gives benzyloxy‐substituted 2‐vinylcyclohexanols. High asymmetric induction is found for the 4‐ or 6‐benzyloxy‐(__Z__)‐octenylboronates 12a and 12c, whereas cycliza
