摘要

A procedure is presented which allows the six-carbon homologation of aldehydes to give the corresponding trienals viathe likely intermediacy of the novel 2- triphenylphosphranylidenemethyl-2H-pyran; application of this methodology to a short synthesis of the marine alarm pheromone, navenone B, is also described.
