The transposition of oxirane-ethanols, through alkoxytin compounds, into oxetane-2-methanols and/or oxolan-3-ols (tetrahydrofuran-3-ols) is dependent upon the oxirane configuration. Cis configuration is more suitable for the formation of the smallest ring. Steric hindrance is not sufficient enough to explain the results.
环氧乙烷-乙醇通过烷氧基锡化合物转位成环氧乙烷-2-甲醇和/或环氧乙烷-3-醇(四氢呋喃-3-醇)取决于环氧乙烷的构型。顺式构型更适合于形成最小的环。立体位阻不足以解释结果。
