One-pot migration–formylation of benzyl aryl ethers under Duff reaction condition
摘要:
A one-pot migration-formylation of benzyl aryl ethers under Duff reaction condition is described. The reaction was performed with HMTA (hexamethylene tetramine) and TFA (trifluoroacetic acid). Under the optimal reaction conditions, a variety of Bn and PMB ethers underwent ortho rearrangement. (C) 2013 Elsevier Ltd. All rights reserved.
This invention relates to agents that are inhibitors or activators of variant forms of endogenous proteins and novel methods of identifying such variants. Of particular interest are inhibitors and activators of endogenous protein variants, encoded by genes which have mutated, which variants often arise or are at least first identified as having arisen following exposure to a chemical agent which is known to be an inhibitor or activator of the corresponding unmutated endogenous protein.

The invention relates to compounds of formula (I) wherein the groups R and R′, A, D, E, G, L, p and R1 to R10 have the stated meanings and to their physiologically compatible salts. Said compounds are suitable, for example, as anti-obesity drugs.
Schiff basefluorescentprobe, namely naphthalic anhydride – (2-pyridine) hydrazone (NAH), has been synthesized and developed for the highlyselective and sensitive monitoring of Fe3+ ions in an aqueous solution and living cells. The enhanced fluorescence emission intensity of NAH has been observed upon the introduction of Fe3+ with a large Stokes shift of 100 nm, and the trace levels of Fe3+ at 38
已经合成并开发了一种席夫碱荧光探针,即萘酸酐–(2-吡啶)((NAH),用于对水溶液和活细胞中的Fe 3+离子进行高度选择性和灵敏的监测。通过引入斯托克斯位移为100 nm的大Fe 3+可以观察到NAH荧光发射强度的增强,并且可以在不受其他现有金属离子干扰的情况下监测38.3 nM的痕量Fe 3+。此外,已经通过ESI-MS,1 H NMR和FT-IR技术讨论了Fe 3+对NAH的识别机理。的绑定方式发现具有Fe 3+的NAH为1:1络合物,其结合常数(K a)为1.77×10 6 M -1。此外,NAH已通过细胞毒性实验证明是无毒的,并成功地证明是活细胞中外源性和内源性Fe 3+传感的良好探针。

Process for preparing 4,6-bis(aryloxy)pyrimidine derivatives A process is provided for preparing 4,6-bis(aryloxy)pyrimidine derivatives. The process is conducted in water as reaction medium and catalyzed by one or more tertiary-amine catalyst(s). It has been found that a water based reaction substantially free of organic solvents can be carried out providing excellent yields by the addition of one or more tertiary-amine catalysts to the reaction medium. This provides a clean reaction and produces the desired product in high yields.
