cis-Hept-4-en-2-ol in corn volatiles: identification and synthesis

Abstract

cis-Hept-4-en-2-ol in Corn Volatiles: Identification and Synthesis Communications ds-Hept-4-en-2-ol was synthesized in 60% overall yield by the oxidation of m-hex-3-enol to ds-hex-3-enal which was then reacted with methylmagnesium iodide. The infrared absorption spectrum of the synthetic sample was identical with that of a sample isolated from corn husk volatiles, confirming that the corn husk hept-4-en-2-ol is in the cis form.

Corn leaf volatiles: indentification using Tenax trapping for possible insect attractants

“…Capillary GLC analysis of the Tenax-trapped volatiles from young corn plant leaves. vacuum steam distillates of corn husk volatiles by some of us- (Buttery et al, 1978;Buttery, 1979). As far as we can determine, (Z)-4-hepten-2-one has not been reported as occurring in any other plant and is therefore one of the most unique volatile compounds associated with corn.…”

Volatiles of corn tassels: possible corn ear worm attractants

“…The volatile compounds associated with the corn plant have been thought to be involved in the attraction of the corn ear worm (Heliothis zea) moth to the corn plant (McMillian and Wiseman, 1972). Volatile components of sweet corn silk, husk, and kernels have already been studied (Flath et al, 1978;Buttery et al, 1978;Buttery, 1979). The tassel is a characteristic part of the corn plant Western Regional Research Laboratory, Science and Education Administration, Agricultural Research, U.S. Department of Agriculture, Berkeley, California 94710. and is thought (cf.…”

New esteric components in the volatiles of banana fruit (Musa sapientum L.)

“…Hex-3(Z)-enal solution in diethyl ether was added to a methylmagnesium iodide solution in diethyl ether. Hept-4(Z)-en-2-ol was isolated in the usual manner (Buttery, 1979). Hept-4(Z)-en-2-yl esters were prepared by a similar manner to that described above and purified with silica gel chromatography.…”
