• Enantioselective Fluorination of β-Ketoesters Catalyzed by Chiral Sodium Phosphate: Remarkable Enhancement of Reactivity by Simultaneous Utilization of Metal Enolate and Metal Phosphate

  A highly enantioselective fluorination of β-ketoesters catalyzed by chiral sodium phosphate is achieved. In this process, the simultaneous formation of sodium enolate and sodium phosphate under basic conditions is the key to achieving excellent selectivity. Indanone derivatives as well as benzofuranone derivatives could be employed in this reaction to afford the fluorinated adducts in good yields with good to excellent enantioselectivities.

  structures of DNA serve as potent chiral scaffolds for DNA-based asymmetric catalysis, yet in most cases tens to hundreds of nucleotides in DNA hybrid catalysts hinder the deep insight into their structure–activity relationship. Owing to the structural simplicity and design flexibility of nucleotides, nucleotide-based catalysts have been emerging as a promising way to obtain fine structural information

  DNA 的不同结构可作为基于 DNA 的不对称催化的有效手性支架，但在大多数情况下，DNA 杂化催化剂中的数十至数百个核苷酸阻碍了对其结构-活性关系的深入了解。由于核苷酸的结构简单性和设计灵活性，基于核苷酸的催化剂已成为获得精细结构信息和理解催化机制的有前途的方法。在此，我们发现环状双 AMP (c-di-AMP) 和 1,10-菲咯啉硝酸铜 (II) (Cu(phen)(NO 3 ) 2 ) 的环状二核苷酸组装成 c-di- AMP 基催化剂 (c-di-AMP/Cu(phen)(NO 3 ) 2)，它可以在水中快速实现对映选择性氟化，产率为 90-99%，对映体过量 (ee) 高达 90%。c-di-AMP 和 Cu(phen)(NO 3 ) 2之间的主客体相互作用主要以超分子相互作用模式提出，紫外-可见、荧光、圆二色性和核磁共振的光谱技术证明了这一点。Cu(phen)(NO 3 )

  A new kind of mono-oxazoline ligands which combined diaryl methyl units and chiral oxazoline units together using pyridine as linker was prepared. Their applications in enantioselective electrophilic fluorination of beta-ketoesters by NFSI were investigated, and the corresponding products were obtained in excellent yield (up to 90%) and good enantioselectivity (78%) in CH2Cl2 at -60 degrees C.
