  • 1,3,5-nonatriene derivatives, their preparation and their use
    申请人:Rhone-Poulenc Sante
    公开号:US04876370A1
    公开(公告)日:1989-10-24
    1,3,5-Nonatriene derivatives of formula: ##STR1## in which R.sub.1 and R.sub.2, together with the carbon atom to which they are linked, form a carbonyl group, or each of R.sub.1 and R.sub.2 denotes alkoxy or R.sub.1 and R.sub.2 together form an alkylenedioxy radical, which may be made by reaction of a butadiene derivative of formula: ##STR2## in which R is alkyl or phenyl, with a butanal ketoacetal of 10 formula: ##STR3## followed by reaction of the product with a halomethyltriphenylphosphonium halide, are useful intermediates e.g. for the production of phytol.
    公式为##STR1##的1,3,5-Nonatriene衍生物,其中R1和R2与它们连接的碳原子一起形成一个羰基,或者R1和R2中的每一个表示烷氧基,或者R1和R2一起形成一个烷二氧基基团,可以通过下列反应制备:将公式为##STR2##的丁二烯生物与公式为##STR3##的戊醛缩醛反应,然后再将产物与卤代甲基三苯基膦卤化物反应。这些中间体可用于生产类胡萝卜素醇。
  • An Efficient Synthesis of the Fully Elaborated Isoindolinone Unit of Muironolide A
    作者:Qing Xiao、Kyle Young、Armen Zakarian
    DOI:10.1021/ol401354a
    日期:2013.7.5
    An efficient stereocontrolled construction of the fully substituted isoindolone subunit of muironolide A is described. The approach is centered on the intramolecular Diels-Alder reaction between the enol form of the beta-keto amide and an alpha,beta,gamma,delta-unsaturated ester, followed by the installation of the cyclohexene double bond.
  • Bromation des enamines du prénal et du crotonaldéhyde. Voie d'accès aux ω-bromo aldéhydes et ω-bromo acétals correspondants.
    作者:Lucette Duhamel、Jerôme Guillemont、Jean-Marie Poirier、Pierre Chabardes
    DOI:10.1016/s0040-4039(00)61186-3
    日期:1992.8
    Bromination of enamines of prenal and crotonaldehyde yields the corresponding omega-bromoaldehydes via the simple hydrolysis of iminium salts. The carbonyl function of these aldehydes can be protected as acetals or dioxolane. The overall process can be realized in a one pot procedure. The dioxolane is the starting material of a phosphonate which allows by condensation with beta-ionylidenacetaldehyde a direct access to the retinal with a 27.5% overall yield from the enamine 2
