Rearrangement of 2,5-bis(silylated)-N-Boc pyrroles into the corresponding 2,4-species.
The rearrangement of 2,5-bis(silylated)-N-Boc pyrroles in their 2,4-isomers is shown to proceed under mild acidic conditions. A reasonable mechanism, based on literature as well as experiments, is proposed to rationalize this transformation.
