Efficient Phosphonium-Mediated Synthesis of 2-Amino-1,3,4-oxadiazoles
摘要:
We present an efficient, room temperature procedure for the preparation of 2-amino-1,3,4-oxadiazoles, Oxadiazol-2-ones can be activated for S(N)Ar substitution using phosphonium reagents (e.g., BOP). This approach provides convenient access to N,N-disubstituted 2-amino-1,3,4-oxadiazoles, which are difficult to prepare using existing synthetic strategies.
