Synthesis of Severely Sterically Hindered Secondary Aminoether Alcohols from a Ketene and/or Carboxylic Acid Halide and/or Carboxylic Acid Anhydride
摘要:
Severely sterically hindered secondary aminoether alcohols are prepared by a process comprising reacting a ketene with sulfuric acid to produce an anhydride which is then reacted with, to cleave the ring of, a dioxane to yield a cleavage product which is then aminated using an amine, followed by hydrolysis with a base to yield the desired severely sterically hindered secondary aminoether alcohol.
