Synthesis of α-Amidoketones from Vinyl Esters via a Catalytic/Thermal Cascade Reaction
A straightforward, modular, and atom-efficient method is reported for the synthesis of α-amidoketones from vinyl esters via a cascade reaction including hydroformylation, condensation with a primary amine, and a rearrangement step giving water as the only byproduct. The reaction sequence can be performed in one pot or as a three-step procedure. The synthetic applicability is demonstrated by the preparation of different α-amidoketones in moderate to good yields.
Use of the composite material RuO2/BaTi4O9 as an environmentally benign solid catalyst for the oxidative cleavage of olefins
Catalytic use of a composite material, RuO2/BaTi 4O9, in combination with NaIO4 in EtOAc-H 2O has been shown to efficiently cleave alkenes, affording ketones, aldehydes and/or carboxylic acids in high yields. Georg Thieme Verlag Stuttgart.
