标题:Synthesis of succinimides and quaternary ammonium ions for use in making molecular sieves
发明人：SCHMITT KIRK D; ZUSHMA STEPHEN; BURTON ALLEN W
权利人:EXXONMOBIL CHEMICAL PATENTS INC
摘要:The present invention relates to the synthesis of succinimides, in particular to a method for the synthesis of a succinimide compound, comprising the step of reacting an alkyne, with carbon monoxide and ammonia or an amine, in the presence of an iron catalyst, wherein the reaction is carried out in an amine liquid phase and/or in the absence of an ether solvent. The succinimides may be reduced to quaternary ammonium cations which may be used as structure directing agents in the synthesis of molecular sieves.

摘要:The present invention relates to an improved process for the large scale synthesis of cyclic heptapeptide using Fmoc solid phase synthesis technique. The described process assembles the peptide on a solid support resin by coupling to one another by peptide bonds to obtain a peptide wherein the coupling of cysteine to the resin employs a combination of solvents to reduce cysteine racemization. The process described relates to the use of C1-C4 alcohols as total substitute to organic nitriles thus making the process cost effective, non-toxic and eco-friendly.
