Herein, we address the challenge of using chitin-derived furans, 3-acetamido-5-acetylfuran (3A5AF) and 3-acetamido-5-furfural aldehyde (3A5F), to favour the formation of exo Diels?Alder adducts and 4-acetylaminophthalimides respectively, using a mechanochemical ball-milling technique. Mechanochemical activation is explored through the synthesis of 7-oxa-norbornene backbones with novel substitution pattern from 3A5AF in yields up to 77 % and improved exo:endo selectivity compared to solution-phase reactions. The synthesis of 4-acetylaminophthalimides from 3A5F in yields up to 79 % is also showcased from hydrazone derivatives.
