Palladium-catalysed coupling of vinyl phosphates with aryl or heteroaryl boronic acids. Application to the synthesis of substituted nitrogen containing heterocycles
Unusual substituted nitrogen-containing heterocycles were prepared in three steps from commercially available derivatives via an extension of the Suzuki reaction involving the palladium-catalysed coupling of vinyl phosphate with aryl or heteroarylboronic acids.
