Condensation of the triisobutylaluminum complex of cysteamine HCl with a variety of carboxylic esters furnishes thiazolines in onestep. This new method has been applied to chiral α-aminoesters to give α-amino thiazolines of high optical purity, yet N-benzyl protection of the amine is required.

Novel picolinamide‐based histonedeacetylase (HDAC) inhibitors were developed, drawing inspiration from the naturalproductpsammaplin A. We found that the HDAC potency and isoform selectivity provided by the oxime unit of psammaplin A could be reproduced by using carefully chosen heterocyclic frameworks. The resulting (hetero)aromatic amide based compounds displayed very high potency and isoform selectivity
从天然产物 psammaplin A 中汲取灵感,开发了新型基于吡啶酰胺的组蛋白去乙酰化酶 (HDAC) 抑制剂。我们发现,通过使用精心挑选的杂环框架,可以重现由 psammaplin A 的肟单元提供的 HDAC 效力和异构体选择性。所得的(杂)芳族酰胺基化合物在 HDAC 家族中表现出非常高的效力和异构体选择性,此外相对于先前报道的 HDAC 抑制剂具有出色的配体效率。特别是,氯吡啶基序提供的高 HDAC1 异构体选择性代表了开发针对 HDAC1 的新先导化合物和化学探针的有价值的设计标准。
