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.

The present invention discloses compounds of Formula (I), or pharmaceutically acceptable salts, esters, or prodrugs thereof: which inhibit Respiratory Syncytial Virus (RSV). The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from RSV infection. The invention also relates to methods of treating an RSV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.
The use of a Mitsunobu reagent for the formation of heterocycles: a simple method for the preparation of 3-alkyl-5-aryl-1,3,4-oxadiazol-2(3H)-ones from carboxylic acids
The reaction of carboxylic acids with Mitsunobu reagents, prepared by the reaction of triphenylphosphine with dialkyl azodicarboxylates, followed by heating at 180-190 degrees C under solvent-free conditions, afforded 3-alkyl-5-aryl-1,3,4-oxadiazol-2(3H)-ones. This facile and convenient method readily provides the 1,3,4-oxadiazolone ring systems in good yields using a one-pot protocol starting from
