An efficient synthesis of the plant growth hormone 1-triacontanol
摘要:
A high yield synthesis of 1-triacontanol was based on the cheap and easily available starting materials 1-octadecanol and 1,12-dodecanediol. The first one was converted to octadecanal using a phase transfer system, whereas the second one after phase transfer bromination and reaction with triphenylphosphine provided 1-hydroxy-12-triphenylphosphonium bromide. Wittig reaction of these two synthons and subsequent hydrogenation furnished the desired product.
