摘要

The reaction of α-(2-pyridylthio) allylstannanes with allylic halides in the presence of a catalytic amount of copper (I) iodide in DMSO-THF produced the 1, 5-dienes 3 in good yields. The γ-selective allylation using allyl chloride followed by the alkylation and hydrolysis of resulting vinyl sulfides gave δ, ε-unsaturated ketones.
