  Efficient Synthesis of 3-Aminocyclobut-2-en-1-ones:  Squaramide Surrogates as Potent VLA-4 Antagonists

  摘要：

  [GRAPHICS]A novel series of uniquely functionalized 3-aminocyclobut-2-en-1-ones has been prepared by facile condensation of a variety of cyclobuta-1,3-diones with a phenylalanine-derived primary amine. These systems subsequently lend themselves to substitution at C-2 by reaction with a variety of electrophilic reagents including N-halosuccinimides, sulfenyl chlorides, and Eschenmoser's salt. Compounds from this novel series are potent antagonists of VLA-4.
