The present invention provides a process for making 3-hydroxyalkanenitriles comprising the steps of reacting an alkenylnitrile, wherein the alkenylnitrile is an alkenyl-2-nitrile or an alkenylnitrile which under reaction conditions isomerizes to form an alkenyl-2-nitrile, in the presence of a base with benzyl alcohol to form a 3-benzyloxyalkanenitrile adduct and then partially hydrogenating the adduct in the presence of a trace amount of HCl to form the 3-hydroxyalkanenitrile or fully hydrogenating the adduct to form a 3-hydroxyaminoalkane.

Iodine activation induces intramolecular hydroboration of homoallylic and bis-homoallylic amineboranes with good to excellent control of regiochemistry compared to control experiments using excess THF•BH3. Deuterium labeling and other evidence confirm that the iodine-induced hydroboration reaction of homoallylic amineboranes occurs via an intramolecular mechanism equivalent to the classical 4-center
