Sequential Hydrozirconation/Cyclization of Dienes, a New Route toward Trans 2-Substituted Vinylcyclopentanes was written by Clergue, Sebastien;Vasse, Jean-Luc. And the article was included in Organic Letters in 2014.Product Details of 19432-68-9 This article mentions the following:
Trans-2-substituted vinylcyclopentanes such as I (R = Ph, 2-BrC6H4, 4-MeOC6H4, 2-thienyl, PhCH2, PhCH2OCH2CH2CH2) were prepared in 25-72% yields and in 2.8:1->19:1 diastereoselectivities by diastereoselective reductive cyclizations of 7-methoxy-1,5-heptadienes such as (E)-H2C:CHCH2CHRCH:CHCH2OMe (R = Ph, 2-BrC6H4, 4-MeOC6H4, 2-thienyl, PhCH2, PhCH2OCH2CH2CH2) mediated by (chloro)(hydrido)zirconocene (Schwartz’s reagent) and Me3SiOTf. In the experiment, the researchers used many compounds, for example, Methyl 2-thienylacetate (cas: 19432-68-9Product Details of 19432-68-9).
Methyl 2-thienylacetate (cas: 19432-68-9) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Product Details of 19432-68-9
