Abstract
Intramolecular allylboration reactions of (8-oxo-2-octenyl)boronates p roceed with excellent diastereoselectivity: the E-isomer 1d leads to t he trans-2-vinylcyclohexanol (2) with 99.5% d.s., the corresponding Z- isomer 3d cyclizes to give the cis-isomer with a diastereoselectivity exceeding 99.8%.
