A Pd-catalyzed CO-free carbonylative synthesis of 4H-benzo[d][1,3]oxazin-4-one derivatives was developed. This new method employed readily available N-(o-bromoaryl)amides as the starting materials and inexpensive benzene-1,3,5-triyl triformate (TFBen) as the stable solid CO surrogate, which would not cause hydrodehalogenation of the starting materials. Remarkably, this method featured a very broad
开发了 Pd 催化的 4 H -benzo[ d ][1,3]oxazin-4-one 衍生物的无 CO 羰基化合成。这种新方法使用容易获得的N -(邻溴芳基)酰胺作为起始原料,使用廉价的三甲酸苯-1,3,5-三酯(TFBen)作为稳定的固体 CO 替代物,不会引起起始原料的加氢脱卤。值得注意的是,该方法具有非常广泛的底物范围,特别适用于将苯并[ d ][1,3]oxazin-4-one结构引入药物和天然生物活性化合物中。

Compositions and methods for the treatment and amelioration of arterial stiffness, hypertension, and/or arterial aging in a subject. In certain embodiments, the active agents of the compositions provide anti-aging treatments by causing arterial remodeling by decreasing collagen production and increasing elastin production in a subject. In certain embodiments, the active agents can be used to treat a subject having diabetes or a diabetes-related disease or condition, such as but not limited to, Type 1 diabetes mellitus (T1DM), Type 2 diabetes mellitus (T2DM), and hyperinsulenima (pre-diabetes). In certain embodiments, the active agents can be used to treat subjects having hypertension, aortic disease, cardiovascular disease, including heart failure (such as congestive heart failure), kidney disease, osteoporosis, Alzheimer's disease, infertility, and emphysema.
