The palladium-catalyzed oxidation of alkyl enolethers to enals, which employs low loadings of a palladium catalyst, is described. The mild oxidation conditions tolerate a diverse array of functional groups, while allowing the formation of di-, tri-, and tetrasubtituted olefins. The application of this methodology to intramolecular reactions of alkyl enolethers containing pendant alcohols provides

system of Saegusa oxidation, which converts enolethers to the corresponding enals with a number of diverse substrates at extremely low catalyst loadings (500 mol ppm) under ligand-free and aqueous conditions, is described. Its synthetic utility was demonstrated by large-scale applications of the catalyst system to important nature molecules. This work allows Saegusa oxidation to become a highly practical

practical reagent for the preparation of vinyl ether with good to excellent yield. This method efficiently effects methoxymethylenation or vinyl ether formation of enolizable, nonenolizable, and sterically hindered ketones. The complexation of Ti–Mg–CHOMe was facilitated, presumably, by THF dramatically increasing the feasibility; and scope of this protocol is to produce vinyl ethers which can be used
Discovery of 6-Phenylpyrimido[4,5-<i>b</i>][1,4]oxazines as Potent and Selective Acyl CoA:Diacylglycerol Acyltransferase 1 (DGAT1) Inhibitors with in Vivo Efficacy in Rodents
The discovery and optimization of a series of acyl CoA:diacylglycerol acyltransferase 1 (DGAT1) inhibitors based on a pyrimido[4,5-b][1,4]oxazine scaffold is described. The SAR of a moderately potent HTS hit was investigated resulting in the discovery of phenylcyclohexylacetic acid 1, which displayed good DGAT1 inhibitory activity, selectivity, and PK properties. During preclinical toxicity studies
描述和优化了一系列基于嘧啶[4,5- b ] [1,4]恶嗪骨架的酰基辅酶A:二酰基甘油酰基转移酶1(DGAT1)抑制剂。对中等强度HTS命中的SAR进行了研究,结果发现了苯基环己基乙酸1,该苯基环己基乙酸显示出良好的DGAT1抑制活性,选择性和PK性能。在临床前毒性研究过程中,观察到代谢物1升高了肝酶ALT和AST的水平。随后,合成类似物以排除有毒代谢物的形成。这项工作导致发现了螺螺茚满42,与1相比,螺螺茚满42显示出对DGAT1抑制作用的显着改善。。Spiroindane 42在啮齿动物体内具有良好的耐受性,在小鼠口服甘油三酸酯摄取研究中显示出功效,并且在临床前毒性研究中具有可接受的安全性。
