Studies on Pyrrolidinones. A Silylated Approach to Fused Triazoles
摘要:
Starting from the readily available bis trimethylsilyl amidrazones derived from iminoether of methyl pyroglutamate, an easy high yield synthesis of functionalized fused triazoles is described.

The compounds of the present invention are novel bicyclic triazole amino acid-derivatives useful as α4 integrin receptor antagonists. The invention is further directed to methods for treating integrin mediated disorders including, but not limited to, inflammatory, autoimmune and cell-proliferative disorders, methods for preparing the compounds and methods for preparing the intermediates, derivatives and pharmaceutical compositions thereof.
