Abstract

This contribution reviews a family of reactions devised in our laboratory that effect the oxidative conversion of phenols into 4-amido-dienones. A salient feature of this chemistry is the use of hypervalent iodine reagents, especially diacetoxyiodobenzene (DIB), as uniquely capable oxidants in the context of the new transformation. The advent of this methodology has created new opportunities in alkaloid synthesis. Our efforts toward FR-901483, TAN-1251C, cylindricine C, and other nitrogenous natural products illustrate some applications in that domain.
