Iminopropadienones from Dioxanediones, Isoxazolopyrimidinones, Pyridopyrimidinones, and Pyridopyrimidinium Olates
摘要:
Iminopropadienones, RN=C=C=C=O, can be generated from four different types of precursors in flash vacuum thermolysis reactions: 1,3-dioxane-4,6-diones 1, isoxazolopyrimidinones 2, pyridopyrimidinium olates 3, and pyridopyrimidinones 4. 2,6-Difluorophenyl-, 2,6-diethylphenyl-, o-tertbutylphenyl-, and mesityliminopropadienone have been directly observed by Ar matrix IR spectroscopy in one or more of these reactions. Reactions with bis-nucleophiles afford pyridopyrimidinones and perhydrodiazepinone derivatives.

non-bile acid FXR agonists that introduce a bicyclic nortropine-substituted benzothiazole carboxylic acidmoiety onto a trisubstituted isoxazole scaffold. Herein, we report the discovery of 1 (tropifexor, LJN452), a novel and highlypotent agonist of FXR. Potent in vivo activity was demonstrated in rodent PD models by measuring the induction of FXR target genes in various tissues. Tropifexor has advanced
Twenty-nine novel triazole analogues of ravuconazole and isavuconazole were designed and synthesized. Most of the compounds exhibited potent in vitro antifungal activities against 8 fungal isolates. Especially, compounds a10, a13, and a14 exhibited superior or comparable antifungal activity to ravuconazole against all the tested fungi. Structure-activity relationship study indicated that replacing
