Characterization and evaluation of synthetic acylsugar on the behavior of the whitefly Bemisia tabaci (Gennadius, 1886) b biotype (Hemiptera: aleyrodidae) in tomato plants was written by Silva, Vanisse de Fatima;Cardoso, Maria das Gracas;Campos de Moraes, Jair;Pimentel, Flavio Araujo;Goncalves, Luciano Donizete;Neri, Danila Kelly Pereira. And the article was included in Ciencia e Agrotecnologia in 2008.Name: (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate This article mentions the following:
Tomato plant growing is an important activity in Brazil both in production and in consumption, and the states of Goias, Sao Paulo and Minas Gerais are the main producing states. To develop new products with insecticide activity, this work was developed with the aim synthesizing acylsugar, allelochem. present in the leaves that give natural resistance to the tomato plant Lycopersicon pennellii evaluating and its effects on the behavior of the whitefly. The layout used was a completely randomized design, with 5 treatments and 5 repetitions. The trials consisted of the following treatments: Santa Clara tomato plants cultivar sprayed with pure water (control); Santa Clara tomato plants cultivar sprayed with acylsugar 01 (synthesized starting from sucrose); Santa Clara plants of tomato cultivar sprayed with acylsugar 02 (synthesized starting from the glucose with chloride of zinc as catalyst); tomato plants Santa Clara cultivar sprayed with acylsugar 03 (synthesized starting from the glucose with acetate of sodium as catalyst) and tomato plants Lycopersicon pennellii splayed with pure water. The concentration of the composition used was of 0.05%. The results showed that the acylsugar 03 reduce the egg laying activity of the whitefly in the tomato plant. However, it seems necessary to deepen studies to evaluate the action of this product on the whitefly behavior. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7Name: (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate).
(2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7) belongs to tetrahydrofuran derivatives. Tetrahydrofurans and furans are important oxygen-containing heterocycles that often exhibit interesting properties for biological applications or applications in the cosmetic industry. Commercial tetrahydrofuran contains substantial water that must be removed for sensitive operations, e.g. those involving organometallic compounds. Although tetrahydrofuran is traditionally dried by distillation from an aggressive desiccant, molecular sieves are superior.Name: (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate
