Inverse Electron Demand Diels-Alder Reactions of 3-Carbomethoxy-2-pyrones. Controlled Introduction of Oxygenated Aromatics: Benzene, Phenol, Catechol, Resorcinol, and Pyrogallol Annulation. Regiospecific Total Synthesis of Sendaverine and a Preparation of 6,7-Benzomorphans
Boger, Dale B.,Mullican, Michael D.
, p. 4033 - 4044 (2007/10/02)
A full investigation of the preparation and Diels-Alder reactions of 3-carbomethoxy-2-pyrones is described.Methods for the preparation of a full range of oxygen-substituted aromatics: benzene, 1-, 2-, or 3-phenol, symmetrical or unsymmetrical o-catechol, resorcinol, and pyrogallol annulation from a common 3-carbomethoxy-2-pyrone intermediate are detailed.A regiospecific total synthesis of sendaverine, a 2-benzyltetrahydroisoquinoline possessing a selectively protected, symmetrical o-catechol, and a preparation of 6,7-benzomorphans are described.
