We report a simple two-step one-flask procedure for the synthesis of tetramesitylporphyrin in 29 percent yield.Pyrrole and mesitaldehyde react at room temperature to form tetramesitylporphyrinogen.The addition of an oxidant yields the porphyrin.Macrocycle formation and oxidative aromatization are thus performed separately.The reaction at higher temperature results in a lower yield of porphyrin.
