Efficient Total Synthesis of Lycophyll (ψ,ψ-Carotene-16,16′-diol) was written by Jackson, Henry L.;Nadolski, Geoffry T.;Braun, Cristi;Lockwood, Samuel F.. And the article was included in Organic Process Research & Development in 2005.HPLC of Formula: 37905-02-5 The following contents are mentioned in the article:
A practical procedure is described for the total synthesis of lycophyll (16,16′-dihydroxy-lycopene; ψ,ψ-carotene-16,16′-diol), based on a C10 + C20 + C10 synthetic methodol. using the com. available materials geraniol (C10) and crocetindialdehyde (C20). A late-stage double Wittig olefination on crocetindialdehyde was used to form the desired lycophyll scaffold in eight linear synthetic steps, while generating a mixture of polyenic geometric isomers that could be effectively separated using HPLC. All-trans lycophyll was subsequently separated to >95% purity by semipreparative chromatog. using a C30 carotenoid column. This study involved multiple reactions and reactants, such as (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5HPLC of Formula: 37905-02-5).
(2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.HPLC of Formula: 37905-02-5
