β-Ketothio derivatives 4, prepared by reaction of phthalimidosulphenyl chloride with enolizable carbonyl compounds, afford, in presence of pyridine, unstable functionalized thiones which can be trapped with 1,3-dienes to give the corresponding cycloaddition products8and9.
通过邻苯二甲酰亚胺基磺酰氯与可烯醇化的羰基化合物反应制得的β-酮硫基衍生物4在吡啶存在下提供了不稳定的官能化硫酮,该硫酮可被1,3-二烯捕获,得到相应的环加成产物8和9。
