E-Isomer {n}chem.
Anwendungsbeispiele Englisch
  • These are the "Z" and "E" strains, named after the stereochemistry of the predominant isomer of 11-tetradecenyl acetate that they produce.
  • Isomeric with nerol is geraniol, which is "trans"- or "E"-isomer.
  • Another classic example is the use of a bulky Lewis acid to form the "E-"isomer of an ester over the preferred "Z"-isomer for cyclolactonization of medium rings.
  • Condensation of "tert"-butanesulfinamide with an aldehyde or ketone proceeds in high yield and affords only the ("E")-isomer of the corresponding "N"-sulfinyl imines.
  • With stabilised ylides the product is mainly the E-isomer, and this same isomer is also usual with the HWE reaction.
  • For most 1,2-disubstituted compounds that exhibit "cis"–"trans" isomerism, the "trans" ("E") isomer is more stable than the "cis" ("Z") isomer.
  • Occurring naturally as predominantly the "trans" ("E") isomer, it gives cinnamon its flavor and odor.
  • Ethyl 2-methylacetoacetate (R=R'=Me) gives the geometrically pure E isomer by this method.
  • It may occur as either the cis "(Z)" or trans "(E)" isomer.
  • The commercial product typically exists as a mixture of 70% ("Z")-isomer and 30% ("E")-isomer.
  • The ("E")-isomer is also one of the starting materials for Birman's total synthesis of the poriferic natural product sceptrin.
  • The registered active form is the "trans"- (i.e. "E"-) isomer.
  • Citral is a collective term which covers two geometric isomers that have their own separate names; the "E"-isomer is named geranial ("trans"-citral) or citral A.
  • The compound is usually sold as a mixture of the "E"- and "Z"-isomers, which differ with respect to the relative position of the methyl and formyl groups.
  • It can undergo reversible photoisomerization induced by ultraviolet light, converting between the "E" and "Z" isomers, both of which are typically colorless compounds.
