Abstract
Hydroboration of the chiral allylic metals.(1a–1e) gave regiospecifically 1,3-diol. Greater than 95% of syn-1,3-diol was obtained with 9-BBN, while a 50:50 mixture of syn and anti-1,3-diol was produced with BH3. The chiral allylic alcohol, 2,2-dimethyl-4-hexen-3-ol (1f), produced anti-1,2-diol.
