Defunctionalization of fructose and sucrose: Iron-catalyzed production of 5-hydroxymethylfurfural from fructose and sucrose

A highly efficient iron-catalyzed production of 5-hydroxymethylfurfural (HMF) from sugar is reported. The dehydration of fructose and sucrose has been studied in the presence of different iron salts and co-catalysts. As a result, it was found that fructose ...

Organometallic complexes that interconvert between trimeric and monomeric structures as a function of pH and their effect on human cancer and fibroblast cells

Paul Joseph Dyson, Rosario Scopelliti, Kay Severin, Wee Han Ang, Zacharias Immanuel Grote

Organometallic half-sandwich complexes based on ruthenium with aminomethyl-substituted 3-hydroxy-2-pyridone ligands exist in aqueous solution as monomeric O,O′-chelate complexes or trimeric metallamacrocycles depending upon the pH. We hypothesized that adm ...

Synthetic studies towards (-)-lemonomycin, synthesis of fused tetracycles

Jieping Zhu

The asym. synthesis of 1,3-lactol-bridged tetrahydroisoquinolines I [R = SiMe2CMe3, CH2Ph; R1 = CH2CH(CO2Me)2; R2 = CO2CH2Ph] was developed. Subsequent cyclizations of I (R = SiMe2CMe3, CH2Ph) under acidic conditions lead to the formation of a tricyclic en ...
