An improved synthesis of 2-diazo-1,3-diketones

The sodium hydride/dibenzo-18-crown-6 ether system was found to be an effective base for the synthesis of 1,3-diketones by the Claisen condensation. The use of potassium fluoride (with or without crown ether) as the base in diazo-transfer reactions extends this reaction to the synthesis of hindered diazo diketones. In the case of isomeric 1,3-diketones, the stereoselectivity of the process considerably rises.

Investigations on the Conformation of 2-Diazo-1,3-diketones

Conformational analyses of 2-diazo-1,3-diketones (2a-f) with bulky substituents are performed by applying 1H- and 13C-NMR measurements in solution (and in solid state).

β-Ketocarboxylic Esters with trans-Enolization

Open-chained β-ketocarboxylic esters 10/11, existing predominantly in the E-configuration 2 of the enol form, can be generated by the introduction of mesityl groups.The energy gain by the intramolecular hydrogen bridge in the Z-configurations 1 is compens
