Top seeding melt texture growth of NdBaCuO pellets in air
Most of NdBaCuO synthesis were realized under oxygen controlled melt growth (OCMG) which allows to avoid the solid solution formation. However, for industrial applications air synthesis is preferable due to its simplicity and its cost. In this work, different seeds and thermal cycles have been investigated in order to optimize the nucleation conditions for the obtention of a single domain. Several criteria have been defined for the choice of the seed. The solid solution Nd1+xBa2−xCu3Oy formed in these air synthesised samples appears in the range of x = 0.10 to 0.15, corresponding to between 60 K and 80 K. The nominal composition and the synthesis conditions (substrate, thermal treatments.) have to be accurately defined in order to avoid neodymium-rich solid solution formation.

applied this method to produce semisynthetic derivatives of the natural products (+)-sclareolide and (−)-eburnamonine, in which the carbonylgroup is proximal to bulky functional groups. Mechanistic insight is also provided from a time course of 19F NMR. Biological evaluation of the natural-product-derived enones led to the identification of a derivative of (−)-eburnamonine with significant cytotoxicity
报道了一种用于羰基的α-甲基化的有效方法,并且该转化通过在烯烃形成过程中容易地消除三氟乙酸盐来完成。该方法代表了在空间障碍情况下对现有方案的改进,并且我们已经证明了该方法在一系列酮,内酰胺和内酯中的实用性。此外,我们已经应用此方法生产了天然产物(+)-香紫苏内酯和(-)-金枪鱼碱的半合成衍生物,其中羰基基团靠近庞大的官能团。还提供19分钟的时间过程的机械洞察力1 H NMR。对天然产物衍生的烯酮的生物学评估导致鉴定出在耐药MDA-MB-231乳腺癌细胞中具有显着细胞毒性(LC 50 = 14.12μM)的(-)-氨丁胺衍生物。
Highly selective trifluoroacetic ester/ketone metathesis: an efficient approach to trifluoromethyl ketones and esters
atom efficient ‘trifluoroacetic ester/ketone metathesis’ has been sincerely witnessed. Enolizable alkyl (at least two non-hydrogen atoms) aryl ketones were found to react readily with ethyl trifluoroacetate under the promotion of NaH to afford trifluoroacetic ester/ketone exchange products, trifluoromethyl ketones (TFMKs), and aromatic acid esters, which were quite different from the general Claisen
