Asymmetric Total Synthesis of Distaminolyne A and Revision of Its Absolute Configuration

The first total synthesis of a marine derived polyacetylene, distaminolyne A, and its enantiomer were achieved from the commercially available undec-10-en-1-ol. A key proline-catalyzed asymmetric α-aminooxylation of an aldehyde intermediate was used to in

Preparation method of (E,E,Z)-10, 12, 14-hexadecatriene acetate, composition and attractant core

The invention relates to a preparation method of (E,E,Z)-10,12,14-hexadecatriene acetate, a Diaphania pyloalis attractant composition and an attractant core, and compared with the prior art, the preparation method of (E,E,Z)-10,12,14-hexadecatriene acetate has the advantages of cheap and easily available raw materials, high reaction yield, simple post-treatment, high isomerization purity of the synthesized compound, clean and environment-friendly process flow, and high activity in field. The Diaphania pyloalis attractant composition based on the (E,E,Z)-10,12,14-hexadecatriene acetate and theattractant core of the Diaphania pyloalis attractant composition have a remarkable moth-luring synergistic effect and can be stably and efficiently used for population monitoring, prevention and control of mulberry borers.

First total syntheses of (Z)-15-methyl-10-hexadecenoic acid and the (Z)-13-methyl-8-tetradecenoic acid

The first total syntheses for the (Z)-15-methyl-10-hexadecenoic acid and the (Z)-13-methyl-8-tetradecenoic acid were accomplished in seven steps and in 31-32% overall yields. The (trimethylsilyl)acetylene was the key reagent in both syntheses. It is proposed that the best synthetic strategy towards monounsaturated iso methyl-branched fatty acids with double bonds close to the ω end of the acyl chain is first acetylide coupling of (trimethylsilyl)acetylene to a long-chain bifunctional bromoalkane followed by a second acetylide coupling to a short-chain iso bromoalkane, since higher yields are thus obtained. Spectral data is also presented for the first time for these two unusual fatty acids with potential as biomarkers and as topoisomerase I inhibitors.
