protecting group in piperidone derivatives was carried out by stirring them in a suspension of SnCl4·(Et2O)2 complex in diethyl ether. When appropriate, the er’s were determined by proton and carbon NMR spectroscopy utilizing (+)-tert-butylphenylphosphinothioic acid and (+)-DBTA as chiralsolvatingagents.
