Synthesis of oxirnes. IV. 2‐pyridinealdoxime methiodides from 2‐picoline methiodides

Abstract The Ortoleva‐King‐Krohnke sequence was used to prepare substituted 2‐pyridinealdoxime methiodides. The methodology was extended to prepare three analogs in which two molecules of 5‐hydroxy‐2‐pyridinealdoxime methiodide were coupled through the 5‐position with dihalides.
