Selective Wittig Reactions for the Synthesis of Variously Substituted 2-Vinylindoles

Article abstract of DOI:10.1055/s-1989-27253

Three selective variants of the Wittig reaction for the syntheses of 2-vinylindoles are described.The reactions are relatively easy to perform, exhibit E-selectivity, and are characterized by a good flexibility with regard to the functional groups present in the vinyl moiety.
