    • It is well-known that asymmetric deprotonation using s -BuLi/(-)-sparteine in THF leads to poor enantioselectivity as THF preferentially coordinates to s -BuLi. However, we have recently shown that highly enantioselective lithiation of phosphine borane 1 in THF is possible using s -BuLi and the (+)-sparteine surrogate. See
