Methyl iodide mediated cleavage of the nitrogen-oxygen bond of isoxazolidines
摘要:
A novel method of N-O bond cleavage in isoxazolidines is described. Treatment of isoxazolidine with excess of methyl iodide in THF under reflux gave the quaternary ammonium iodide alcohol and the alpha,beta-unsaturated aldehyde. The former can be converted to the latter via the Swern oxidation. (C) 1997 Elsevier Science Ltd.
