Rearrangement of acyloxyoxiranes to α-acyloxyketones, in situ, was observed. The α-ketoacetate structure assigned previously to the m-CPBA oxidation product of 5α-androst-16-ene-3α,17-diol 3-benzoate 17-acetate, has been revised to an acyloxyoxirane structure based on spectroscopic and X-ray diffraction data.
在间氯过苯甲酸将共轭烯酮氧化为α-酰氧基氧杂环丁烷的过程中,优选的顺序是环氧化,然后进行Baeyer-Villiger氧化。观察到酰氧基肟酮原位重排为α-酰氧基酮。基于光谱和X射线衍射,先前分配给5α-雄烯-16-烯-3α,17-二醇3-苯甲酸酯17-乙酸酯的m-CPBA氧化产物的α-酮乙酸酯结构已被修改为酰氧基环氧乙烷结构数据。
