  One-Pot Homolytic Aromatic Substitutions/HWE Olefinations under Microwave Conditions for the Formation of a Small Oxindole Library

  摘要：

  An efficient one-pot sequence comprising a homolytic aromatic substitution followed by an ionic Horner-Wadsworth-Emmons olefination for the preparation of a small library of alpha,beta-unsaturated oxindoles is presented. Microwave-induced heating is used to conduct these reactions. The homolytic aromatic substitution is mediated by the persistent radical effect.

  developed to provide rapid access to 3-alkenyl-oxindoles from α-halo-anilides. This one-pot microwave accelerated process proceeds with catalytic palladium(II) acetate or tetrakis(triphenylphosphine)palladium, and has been used to prepare a range of adducts derived from aromatic, heteroaromatic and aliphatic aldehydes. The procedures can be used to prepare N-unprotected oxindoles directly and the applicability
