An efficient and selective domino Heck/Buchwald–Hartwig arylations of readily available N‐glycosylcinnamamides with aryl iodides have been established. Using palladium(II) acetate as a catalyst, potassium acetate as the base and tetrabutylamonium bromide as an additive in dioxane, the protocol proved to be general, and a variety of 4‐aryl‐N‐glycosylquinolin‐2‐ones has been prepared in good yields with

This invention relates to the discovery of novel compounds, or pharmaceutically acceptable salts thereof, which possess HDAC inhibitory activity. In particular, the compounds of the invention demonstrate selectivity towards Class I HDAC enzymes, and are accordingly expected to be useful for their anti-proliferative activity and in methods of treatment of the human or animal body, for example in preventing or inhibiting tumour growth and metastasis in cancers. The invention also relates to processes for the manufacture of the compounds defined herein, or pharmaceutically acceptable salts thereof, to pharmaceutical compositions containing them and to their use in the manufacture of medicaments for use in the production of an anti-proliferative effect in a warm-blooded animal such as man.

Arylsulfonyl group-bearing α,β-unsaturated enol esters were readily assembled via the Cs2CO3-mediated union of 2-bromoallyl sulfones and cinnamic acids. The overall transformation is equivalent to an sp2 carbon–oxygen coupling reaction, and therefore constitutes a formal vinylic substitution. Several of the products display promising levels of antiproliferative activities higher than that of the anticancer
带有芳基磺酰基的α,β-不饱和烯醇酯很容易通过Cs 2 CO 3介导的2-溴烯丙基砜和肉桂酸的结合来组装。整个转化相当于 sp 2碳-氧偶联反应,因此构成了正式的乙烯基取代。其中几种产品显示出比抗癌药物卡铂更高的抗增殖活性,有前景。苯硫酚与 2-溴烯丙基砜在相同条件下反应,通过明显的空气氧化得到 α-苯硫基-α'-甲苯磺酰丙酮。

A fast and efficient nickel-catalysed iodination reaction of aryl and heteroaryl bromides has been developed. The transformation was found to be general for a wide range of substrates and was used for the synthesis of iodo-PK11195, an imaging agent of Alzheimer's disease and iniparib, a compound used in the treatment of breast cancer.

skyllamycins are a family of highly functionalized non‐ribosomal cyclic depsipeptide naturalproducts which contain the extremely rare α‐OH‐glycine functionality. Herein the first total synthesis of skyllamycins A–C is reported, together with the biofilm inhibitory activity of the naturalproducts. Linear peptide precursors for each naturalproduct were prepared through an efficient solid‐phase route incorporating
