Carbon transfer reactions of functionalized oxazolidines and their open chain enamine tautomers to enamine nucleophiles. A facile synthesis of substituted pyridines …
Oxazolidines substituted at C-2 with-CH2-EW (-CO-, etc.) and capable of existing as ring- chain (enamine) tautomers1 react with cyclic, acyclic and heterocyclic enamine derivatives in a 1: 1 stoichiometric manner to provide a versatile synthesis of substituted pyridines and their ring annulated derivatives.
