The phosphonate-phosphate and phosphate-phosphonate rearrangements and their applications, VI: Metallation of phosphorylated aliphatic alcohols to configurationally stable α-oxyalkyllithium compounds - use of the phosphoryl group as an activating group and electrophile

Alkyl diisopropyl phosphates were metallated by sBuLi/TMEDA at -78 °C at the alkyl and isopropyl group in a ratio which is strongly influenced by steric effects. The regioselectivity of deprotonation was very high by use of heptadeuterioisopropyl groups, which reflects a high primary kinetic isotope effect (k(H)/k(D) ≥ 100). The dipole stabilized, phosphoryloxy-substituted alkyllithium compounds formed are configurationally stable and rearrange with retention of configuration (phosphate-phosphonate rearrangement).
