Simple, parallel and dynamic: asymmetric hydroboration reactions of racemic intramolecular Diels‐Alder furan (IMDAF) cycloadducts give regiodivergent outcomes in which simple, parallel and dynamic kineticresolutions of the substrate enantiomers may be observed. We report parallelkineticresolution of intramolecular Diels‐Alder cycloadducts, where up to five stereocentres are defined using asymmetric

prepared from primary aliphatic amines and benzylamine together with formaldehyde and either ethanol or methanol; they were reacted with electrophiles to give N-alkyl-N-alkoxymethyl-methyleneiminium salts which gave mixtures of secondary and tertiaryamines in reactions with electron rich aromatic compounds: sequential reactions with two different nucleophiles gave the expected tertiaryamines.
