This disclosure provides novel compounds and methods for inhibiting BAX activity and BAX-mediated apoptosis, as well as compounds and methods for treating or preventing BAX- mediated disorders.
developed for the N-triflination of pyrazolones using CF3SO2Na (Langlois reagent) and phenyliodine(III)bis(trifluoroacetate) (PIFA). This reaction takes place at the imine nitrogen centre instead of the more reactive C4-position, forming a new N–S bond. A variety of pyrazolone derivatives were subjected to the reaction. Unlike the previous reports on sulfenylation or sulfonylation of pyrazolone, wherein

A one-flask thioetherification of pyrazolones has been demonstrated by transforming several pyrazolones to their corresponding 4-mercaptopyrazolone derivatives and employing them towards cross-coupling with various aromatic and heteroaromatic iodides by applying Pd(OAc)2/xantphos as the catalytic system. The coupling ability of these thiol intermediates with 2,3-dichloropyrazine through an aromatic

(E)‐2‐(hetero)arylethenesulfonyl fluorides and (E,E)‐1,3‐dienylsulfonyl fluorides are bis‐electrophiles and rare members of the sulfonyl fluoride family with limited information being known of their reactivity and synthetic utility. The direct annulation reaction of these 2‐substituted ethenesulfonyl fluorides with medicinally important enolizable pyrazolones and 1,3‐dicarbonyl compounds utilizing catalytic DBU
