Synthesis of Spiropyrrolines via One-Pot Tf2O-Mediated Amide Activation/Formal [3 + 2]-Cycloaddition of α-Formylamino Ketones
The Journal of Organic Chemistry.
An efficient method for the synthesis of spiropyrrolines from readily accessible α-formylamino ketones is reported. The method involves amide activation using Tf
