Relevant academic research and scientific papers

Total synthesis of (±)-phaseic acid

A highly stereoselective synthesis of (±)-phaseic acid is described. Photochemical reaction of the nitrite derived from trans-4-hydroxy-2,2,6-trimethylcyclohexanone functionalizes the methyl group of the geminal pair cis to the hydroxyl group of the start

Syntheses of (±)-methyl 6′ α-demethyl-6′ α-cyanoabscisate and (±)-methyl 6′ α-demethyl-6′ α-methoxycarbonylabscisate

New abscisic acid analogs possessing a cyano or methoxycarbonyl group at the 6α-position of methyl abscisate were synthesized by regioselective hydrocyanation. These compounds had weak activity in the rice second leaf sheath elongation test.

STEREOCONTROLLED SYNTHESIS OF BOTH THE ENANTIOMERS OF PHASEIC ACID AND ITS METHYL ESTERS, A PIVOTAL METABOLITE OF ABSCISIC ACID.

Both the enantiomers of phaseic acid 2a and its methyl ester 2b were synthesized in highly stereocontrolled manner starting from ethyl (1R,2S)-5,5-ethylenedioxy-2-hydroxycyclohexanocarboxylate 5 of 98.4 percent e.e. 6-Oxabicyclooctenone 16 was empl

Glycinoeclepins, Natural Hatching Stimuli for the Soybean Cyst Nematode, Heterodera Glycines. I. Isolation

Hatching stimuli, designated as glycinoeclepins, for the soybean cyst nematode (Heterodera glycines) have been isolated by repeated chromatography of the aqueous extracts of dried roots of kidney bean (Phaseolus vulgaris), one of the host plants of the nematode.One of these compounds, glycinoeclepin A, stimulates the hatching and emergence of larvae in vitro in highly diluted aqueous solutions.

Total Synthesis of (+/-)-Methyl Phaseates

(+/-)-Methyl phaseates were synthesized from (+/-)-4-(6'-acetoxymethyl-2'-6'-dimethyl-1'-cyclohexen-1'-yl)-but-3-en-2-one (20), which was prepared from a useful terpenoid building block, (+/-)-2-hydroxymethyl-2,6-dimethyl-1-cyclohexanone (11a and 11b).Pho
