2-unsubstituted-1-methoxyindoles, based on our methodology for the synthesis of 1-methoxyindoles, is reported. This synthesis renders accessibility to a variety of natural products possessing the said skeleton. A direct synthesis of phytoalexin (1), (±)-paniculidine B (2), and (±)-paniculidine C (3) is disclosed based on the methodology. The synthesis of paniculidineB (2) has been achieved from aldehyde 10 in only two
