Abstract
(2‐(1,3‐Dithianyl))myrtanylborane (MDBH~2~), a stable asymmetric monoalkylborane, was converted into deuterated or tritiated analogues used to prepare enantiomeric labelled alcohols from 1‐phenylcyclopentene with a high isotopic enrichment (90–95% for deuterium; 86–89% for tritium) and a high asymmetric induction (80% ee for deuterium; 75% ee for tritium).
