Abstract

Abstract Kaempferol (1), a natural product from various plants, was synthesized in which the longest linear sequence is only seven steps in over all yields of 47% from commercially avail able 1, 3, 5-trimethoxybenzene (10). The methylated kaempferols 2–5 were also pre pared by use of this concise synthetic methodology. The key transformations in this synthesis involved the I 2 oxidative-promoting-cyclization and DDO oxidative hydroxylation. Several ...
