Regioreversed reactions of the trimethylsilyl or phenylselenyl allylic carbanion with carbonyl compounds via allylic aluminum “ate” complexes was written by Yamamoto, Yoshinori;Saito, Yoshikazu;Maruyama, Kazuhiro. And the article was included in Tetrahedron Letters in 1982.Recommanded Product: 50767-78-7 The following contents are mentioned in the article:
The Et3Al ate complexes of anions of RCH2CH:CH2 (I; R = Me3Si, PhSe) reacted with carbonyl compounds at the α-position with high regioselectivity. E.g., lithiation of I (R = Me3Si), followed by addition of Et3Al and EtCHO gave 94% HOCHEtCH(SiMe3)CH:CH2. The stereoselective synthesis of (E)-CH2:CHCH:CH(CH2)8OAc, a pheromone of Diparopsis castanea, by this method is reported. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Recommanded Product: 50767-78-7).
(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
