通过使用关键的膦酸酯,环状酮和芳基格氏成分的收敛路线,可实现(±)-催眠素的全合成。天然催眠素的1 H和13 C NMR光谱与合成化合物的光谱不一致。特别地,对于天然和合成化合物,分配给质子的信号与内酯羰基周围的碳之间存在相当大的差异。NMR数据强烈表明,天然存在的化合物hyptinin是合成化合物的结构异构体。根据合成结果,最终将天然化合物的结构确定为(+)-β-鬼臼苦素。

A library of pyrido[2,3-d]pyrimidines was designed as inhibitors of FGFR3 tyrosine kinase allowing possible interactions with an unexploited region of the ATP binding-site. This library was built-up with an efficient step of click-chemistry giving easy access to triazole-based compounds bearing a large panel of substituents. Among the 27 analogues synthesized, more than half exhibited 55–89% inhibition of in vitro FGFR3 kinase activity at 2 μM and one (19g) was able to inhibit auto-phosphorylation of mutant FGFR3-K650M in transfected HEK cells.

A collection of benzotriazoles consisting of seven compounds was prepared from the propynyl-substituted benzolactone 1 and various azides usingclickchemistry. The lactone 1 was obtained through a short route by direct esterification of the allylbenzoic acid 9 with the alkynol 7 giving the benzoate 2. The homopropargyl alcohol 7 in turn was obtained by opening the epoxide 6 with triisopropylsilyl

The substitutedbenzamides are used clinically both as antipsychotics and as stimulants of gastric motility. The antipsychotic effects are considered to be a consequence of their central dopamine antagonist properties, but there is evidence that the gastric stimulatory effects may be mediated by other mechanisms. Clebopride (3) is a substitutedbenzamide that although marketed for its stimulatory effects
A totalsynthesis of (±)-hyptinin was achieved via a convergent route using the key phosphonate, cyclic ketone, and aryl Grignard components. The 1H and 13C NMR spectra of natural hyptinin did not agree with those of the synthesized compound. In particular, there were considerable differences between the signals assigned to the protons and carbons surrounding the lactone carbonyl group for the natural
