title: Ammonium chloride promoted three-component synthesis of 5-iminooxazoline and its subsequent transformation to macrocyclodepsipeptide.
abstract: A three-component reaction of an alpha,alpha-disubstituted alpha-isocyanoacetamide, an aldehyde and an amino alcohol afforded the 5-iminooxazoline, which, upon saponification, cyclized under acidic conditions to provide the macrocyclodepsipeptide in good overall yield.
