Selective metal-free amination and Diels-Alder reactions are described in the furan series, leading to polysubstituted anilines or to stable oxabicyclic adducts in high yield. Interestingly, anilines are conveniently prepared through a novel one-pot, two-step amination/Diels-Alder procedure from commercially available 5-bromo-2-furaldehyde.

[reaction: see text] The Suzuki-Miyaura cross-coupling reaction of N,N-dialkylaminomethyltrifluoroborates with aryl halides allows the construction of an aminomethyl aryl linkage through a disconnection based on dissonant reactivity patterns. A variety of these aminomethyltrifluoroborate substrates were prepared in good to excellent
