The irradiation of hypoiodites generated from cyclobutanols prepared by means of N-methylation and hydrolysis of 2+2 photocycloadducts between 4-acetoxy-2-quinolone and cyclopentene or 2,3-dimethylbut-2-ene induced rearrangements of the corresponding alkoxy radicals to give 2,3-furanoquinol-4-ones or a ring expanded product.
由 4-乙酰氧基-2-喹诺酮和环戊烯或 2,3-二甲基丁-2-烯之间的 2+2 光环加合物的 N-甲基化和水解制备的环丁醇产生的次碘酸盐的辐照诱导相应烷氧基的重排,得到2,3-furanoquinol-4-ones 或扩环产品。
