A novel solid-phase approach toward classical cannabinoids is described. The desired tricyclic natural product analogues are assembled in only four atom economic steps: domino oxa-Michael-aldol condensation, Wittig reaction/enol-ether formation, Diels–Alder cycloaddition and cleavage. The synthesis is designed to allow combinatorialchemistry at several stages of the sequence. The variation of commercially
