Abstract
AbstractReactions of aliphatic branched aldehydes with proline in dimethyl sulfoxide or acetonitrile solution afford oxazolidin‐5‐ones with high diastereoselection. Linear aldehydes afford aldolic/crotonic condensation products; with short reaction times, the presence of Oxazolidinones can be detected in the pmr spectra. Acyclic aminoacids and branched aldehydes yield a reaction mixture the pmr and ir spectra of which give evidence for iminic‐oxazolidinone equilibria. The structure of (2R,5S)‐2‐trichloromethyl‐1‐aza‐3‐oxabiciclo‐[3.3.0]octan‐4‐one has been confirmed by X‐ray diffraction analysis.
