A series of 2,2-disubstituted 5,6-diphenyl-4H-1,3-oxathiin-4-ones was synthesized by cycloaddition of thiones with benzoylphenylketene, which was generated by the thermal Wolff rearrangement of 2-diazo-1,3-diphenyl-1,3-propanedione. © 2001 John Wiley & Sons, Inc. Heteroatom Chem 12:630–632, 2001
通过硫酮与苯甲酰基苯基乙烯酮的环加成反应合成了一系列 2,2-二取代的 5,6-二苯基-4H-1,3-oxathiin-4-ones,苯甲酰苯基乙烯酮是通过 2-diazo-1,3 的热沃尔夫重排生成的-二苯基-1,3-丙二酮。© 2001 John Wiley & Sons, Inc. 杂原子化学 12:630–632, 2001
