  • Publication number: 20120157658
    Abstract: This invention relates to methods, compositions, and apparatuses for producing macrocyclic compounds. First, one or more reactants are provided in a reaction medium, which are capable of forming the macrocyclic compound through a desired reaction pathway that includes at least cyclization, and which are further capable of forming undesired oligomers through a undesired reaction pathway that includes undesirable oligomerization. Oligomerization of such reactions in the reaction medium is modulated to reduce formation of undesired oligomers and/or to reduce separation of the undesired oligomers from the reaction medium, relative to a corresponding unmodulated oligomerization reaction, thereby maximizing yields of the macrocyclic compound. The macrocyclic compound so formed is then recovered from the reaction medium. Preferably, the macrocyclic compound spontaneously separates from the reaction medium via phase separation.

  • Patent number: 7147800
    Abstract: A method for making platform molecules comprising: reacting 4-alkoxy benzoyl chloride with R2-hydroquinone under first conditions effective to produce bis 1,4[4-alkoxy-benzoyloxy]-R2-phenylene comprising bis terminal alkoxy groups wherein R2 is a bulky organic group; and, subjecting the bis 1,4[4-alkoxy-benzoyloxy]-R2-phenylene to second conditions effective to selectively cleave the bis terminal alkoxy groups to produce a solution comprising complexes comprising diphenolic platform molecules comprising bis terminal hydroxyl groups, the second conditions also being effective to precipitate the complexes out of the solution.
