The iodonium ion mediated ring expansion of the olefinic cyclobutanols 19, 20, and 22 gave the mixture of iodoalkylated cyclopentanones 27a–c and 28a–c, respectively. On the other hand, the same reaction of 24 – 26 afforded stereoselectively the iodoalkylated cyclopentanones 27d and 27e.
碘鎓离子介导的环扩展烯烃cyclobutanols的19,20,和22给iodoalkylated环戊酮的混合物27A-C和28A-C分别。在另一方面,在同一反应24 - 26立体选择性地得到iodoalkylated环戊27D和27E。
