The reaction of α-trifluoroacetoxy acrylates and acrylonitriles with carbon radicals formed from carboxylic acids gives adducts that can be transformed into vic-diols, esters, amides, and homoaldehydes in good to high yield. Aldoses can be smoothly degraded to the corresponding nor- or bis-nor compounds using radical chemistry.
α-三氟乙酰氧基丙烯酸酯和丙烯腈与选自羧酸形成的碳自由基的反应给出了可以转化成加合物VIC -diols,酯,酰胺,和homoaldehydes以良好至高产率。使用自由基化学可以将醛糖平稳地降解为相应的nor-或bis-nor化合物。
