Some of the enantiopure phospholane oxides 116 were used for further transformations. For example, they could be isomerised by treatment with base for several hours in a protic solvent to afford 117 or subjected to a second deprotonation to produce 118 as a single isomer. Attempts to prepare Z)w(phospholanes) by double nucleophilic attack of the anions derived from 116 were unsuccessful. Some of the phospholane oxides were reduced with tri-chlorosilane/pyridine to afford the free phospholane with retention of configuration. The same strategy was applied to 1-phenylphospholane oxide but low yields of racemic products were obtained. This suggests that substrate 115 is probably a special case due to the formation of a more stable benzylic carbanion. ...
