Syntheses of labelled methyl malvalate

Journal of the Chemical Society D: Chemical Communications, 1970
Practical syntheses of homogeneous methyl malvalate, adaptable for inserting radiocarbon at positions 1, 9, 10, and ring CH2, are described.

Separation of methyl malvalate from methyl sterculate

Journal of the American Oil Chemists' Society, 1981
AbstractMethyl malvalate and sterculate, labile and differing by a single methylene, are difficult to separate completely. They have been separated in our laboratory by high vacuum spinning band distillation. Each of these fatty esters has been prepared completely free of the other.

Syntheses of C-14 labeled methyl malvalates

Chemistry and Physics of Lipids, 1971
Abstract Malvalic acid, the principle cyclopropene acid in cottonseed oil, has been synthesized with carbon-14 at the 1-position, at the ring methano-position, and at the 10-position. A method for reaching malvalic-9- 14 C acid has also been worked out.

Mass spectra of methyl sterculate and malvalate and 1,2-dialkylcyclopropenes

Chemistry and Physics of Lipids, 1974
Abstract The mass spectra of 1,2-dipropyl-, 1,2-dipentyl-, 1,2-dihexyl-, 1,2-diheptyl-, and 1,2-dioctyl-cyclopropene, methyl malvalate, methyl sterculate, malvalyl alcohol, 1,2-dipropyl-, 1,2-dipentyl-, and 1,2-dihexylcyclopropene-3-carboxylic acid, and methyl-9,10-(carbethoxymethano)-9-octadecenoate are presented.

New Ring Opening Oxidation of Methyl Sterculate and Malvalate

Chemistry Letters, 1990
Abstract Air oxidation of cyclopropane fatty acid methyl esters, methyl sterculate and malvalate, resulted in the cleavage of cyclopropene ring, respectively, to afford a pair of conjugated enones containing a terminal methylene group.

Wood Anatomy of Craigia (Malvales) from Southeastern Yunnan, China

IAWA Journal, 2006
Wood anatomy of Craigia W.W. Sm. & W.E. Evans (Malvaceae s.l.), a tree endemic to China and Vietnam, is described in order to provide new characters for assessing its affinities relative to other malvalean genera. Craigia has very low-density wood, with abundant diffuse-in-aggregate axial parenchyma and tile cells of the Pterospermum type in the ...

Cytinaceae are sister to Muntingiaceae (Malvales)

TAXON, 2007
The holoparasitic family Cytinaceae (Cytinus and Bdallophyton) was previously shown to be allied with Malvales, however its closest photosynthetic ancestor was not determined. A molecular phylogenetic study was conducted using nuclear small‐subunit rDNA and three chloroplast genes (the latter missing from the holoparasites but included to stabilize the

Phylogenetic Systematics of Cochlospermaceae (Malvales) Based on Molecular and Morphological Evidence

Systematic Botany, 2017
Abstract Cochlospermaceae (Malvales) is a small family of two genera, Amoreuxia and Cochlospermum. Cochlospermum has a pantropical distribution with species present in Mexico, Central and South America, the West Indies, Africa, India, Southeast Asia, and northern Australia, whereas Amoreuxia has a more restricted distribution in the Americas.
