Novel One‐Pot Access to Diastereoisomeric Tertiary Phospholanes Oxides by Using Enantiomerically Pure Phospholane Oxides Under Catalyst‐Free Conditions

For the first time, enantiopure 1‐ r ‐oxo‐2‐ c ,5‐ t ‐diphenylphospholane was introduced as nucleophile in the multicomponent condensation reaction. Diastereoisomers of 2,5‐diphenyl‐1‐oxo‐1‐[alkylphenyl‐1‐(phenylamino) methyl] phospholane derivatives were synthesized by one‐pot process from aromatic aldehydes, anilines and enantiopure1‐ r ‐oxo‐2‐ c ,5‐ t ‐diphenylphospholane under green and eco‐compatible conditions. The reaction proceeds under...
