An Efficient Synthesis of the Plant Growth Hormone 1-Triacontanol
Tran-Thi, N. H.,Falk, H.
, p. 565 - 568 (1995)
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. - Keywords: 1-Triacontanol: Wittig reaction; Phase transfer reaction; Plant growth hormone
SYNTHESIS OF TRIACONTAN-1-OL FROM DODECANEDIOIC ACID
Zakharkin, L. I.,Aksenova, N. P.,Guseva, V. V.,Bavrina, T. V.,Konstantinova, T. N.,Chailakhyan M. Kh.
, p. 344 - 345 (1984)
A method has been developed for obtaining triacontan-1-ol - a natural plant growth stimulator.Synthesized triacontan-1-ol has an appreciable influence on the growth and crop yield of tomatoes and on the flowering of asters.

Page/Page column 8, (2010/02/11)
The invention relates to protected alcohol with formula (R1 - O-)mPG, wherein R1 represents a linear, straight-chain alkyl group having 26-30 C-atoms, m is 1 or 2, and PG, forming an ether group in combination with the -O- of the former primary alcohol, represents a protecting group chosen from the group of substituted methyl, substituted ethyl, substituted benzyl and (substituted) silyl groups with at least one substituent on the Si-atom being not a methyl group, in case m = 1; and a diol protecting group in case m = 2, with the proviso that PG is no saccharide. The invention further relates to process for the preparation of such protected alcohols via an organometallic cross coupling reaction.
