From 2-aminonorbornene hydroxamic acids, a simple and efficient method for the
preparation of pyrrolo[1,2-a]pyrimidine enantiomers is reported. The synthesis is based on domino
ring-closure followed by microwave-induced retro Diels-Alder (RDA) protocols, where the chirality
of the desired products is transferred from norbornene derivatives. The stereochemistry of the
synthesized compounds was proven by X-ray crystallography. The absolute configuration of the
product is determined by the configuration of the starting amino hydroxamic acid.
