A convenient one-pot synthesis of 5-carboxyisoxazoles: trichloromethyl group as a carboxyl group precursor
摘要:
The one-pot synthesis of ten 5-carboxyisoxazoles from the cyclocondensation of beta-alkoxyvinyl trichloromethyl ketones [CCl3C(O)C(R-2)=C(R-1)OR, where R-1, R-2=H, Me and R=Me, Et] and 2-trichloroacetyl cyclohexanone with hydroxylamine is reported. This work shows that the trichloromethyl group attached to beta-alkoxyvinyl trichloromethyl ketones (a heterocyclic CCC building block) is an excellent carboxyl group precursor.

Respiratory syncytial virus (RSV) represents a threat to infants, the elderly, and the immunocompromised. RSV entry blockers are in clinical trials, but escape mutations challenge their potential. In search of RSV inhibitors, we have integrated a signature resistance mutation into a recombinant RSV virus and applied the strain to high-throughput screening. Counterscreening of candidates returned 14

facile synthesis of a series of 3,5-substituted-1,2,4-oxadiazole derivatives in good to excellent yields. The anti-inflammatory potential of the newly synthesized compounds was evaluated by anti-denaturation assay using diclofenac sodium as the reference standard. Some of the compounds exhibited profound activity profile when compared to the standard drug. The molecular docking and SAR studies were carried
