Ammonia borane is an attractive example of a chemical hydride because its hydrogen storage capacity approaches a whopping 20 percent by weight. Matos highlighted the recently developed new amine borane, 5-ethyl-2-methylpyridine borane (PEMB), as an excellent reducing agent for reductive amination. The authors cover practical features of stability, reactivity, and workup, as well as such aspects of allylboration as the stereochemical control elements, including relative diastereoselection with crotylboranes, induced (internal) diastereoselection with chiral carbonyl compounds, auxiliary-controlled enantio-selective allylations with chiral borane reagents, and recent advances in catalysis of allylboration. |
