Endo and Exo Diels–Alder Adducts: Temperature-Tunable Building Blocks for Chemical Functionalization
Abstract: The development and application of a novel endo furan-protected maleimide building block is reported. The endo isomer undergoes deprotection at temperatures ∼50 °C below the exo derivative. This enables a simple and powerful approach to quantitatively and selectively introduce functional maleimide groups via temperature modulation.
