INTRODUCTION. Macrocyclic compounds have attracked a lot of chemistsbecause of their diverse physical and chemical properties. There was anidealized method to synthesis macrocyclo polyketones compounds. Product(Ⅱ)was obtained by condensation reactions of furan with acetone followed byOxidative opening of furan rings in (Ⅰ) . The 2,2,7,7,12,12,17,17-octamethylcycloeicosan-1,3,6,8,11,13,16,18-octaone(Ⅲ) was obtained byhydrogenation of (Ⅱ) with 20% Pd carried on carbon.
INTRODUCTION. Macrocyclic compounds have attracted a lot of chemists because of their diverse physical and chemical properties. There was an externalized method to synthesize macrocyclo polyketones compounds. Product (II) was obtained by condensation reactions of furan with acetone followed by Oxidative opening of furan rings in ).
