Disubstituted endo tricyclic lactones have been prepared by the reaction of primary alkylmagnesium compounds with the endo bicyclo[2.2.1]hept-5-ene-2, 3 dicarboxylic anhydride. These lactones were alkylated and transformed into corresponding 3,5,5-trialkyl-2(5H) furanones.
通过伯烷基镁化合物与内环双环[ 2.2.1 ]庚-5-烯-2,3二羧酸酐的反应制备了二取代三环内酯。将这些内酯烷基化并转化成相应的3,5,5-三烷基-2(5H)呋喃酮。
